Video Summary
AI GeneratedThis video analyzes the history of official United States military invasions involving ground troops. It examines the strategic motivations—ranging from territorial expansion and economic interests to geopolitical stability—across over 100 conflicts, highlighting a pattern of projecting power abroad rather than fighting on the domestic mainland.
The United States. Ever since their declaration
of independence in 1776, the United States have
been a part of many wars.
After all, their independence was forged in a revolutionary
war against the British.
This isn't a one of a kind example, by the contrary, a large number
of countries throughout history achieved
their independence through war. One other example is
Portugal fighting against Castile to become its own kingdom.
But throughout its almost 250 years
of existence, military conflicts have been a big part
of the United States' existence. Again,
not an exception, it has been so for almost all countries,
although the US do set themselves apart
for being involved in more recent conflicts than other nations.
Throughout all their history,
when it comes to official conflicts,
there have been at least 106 of them. In 81, they were
victorious. Only 10 times they were defeated
with the first defeat only coming in 1866 so they went
almost 100 years undefeated. That is impressive.
11 of them were either unresolved, settled with
a pre-war status quo or unclear and four of them are still ongoing.
Although remember the size of
these wars is not considered,
World War II is listed as a win in the same way the occupation
of Utah against the Mormon colonists
is but through all of those conflicts some wars that
the U.S. was a part of were defensive others were offensive
but in many wars categorized as either
one thing happened u.s invasions you see other than
the revolutionary war itself some other early
wars with british mexicans and native americans
and then the civil war there's been no war fought
in the continental united states for a long time
in the latter you can even consider it a foreign
invasion as it was Americans vs Americans.
Even in World War II, the Contiguous 48 saw
no conflict in their own land and only Hawaii
and other Pacific Islands were invaded by the
Japanese. This is because in every other war
that the US were a part of, whether having started the
conflict or not, they were the invading force fighting
the battle in another country's
territory. In this video, we're going to do two things.
First, provide a brief overview of all
the conflicts the US have been a part of throughout its history,
where an invasion took place,
not listing them all in detail but learning where they happened.
Second, choose a few key examples
of those and go through them specifically understanding when,
why and how some countries
were invaded by the United States.
Let's move forward with the overview. It's important to
note that it's difficult to categorize all conflicts
that the US have been a part of,
especially the ones that they invaded a country in,
not only do they differ in the type of conflict
that it was, whether it was fought on land, sea,
air or a combination of those, posing the question
do we only consider an invasion if it was done
with boots on the ground. I will use this criteria
for the video, excluding conflicts that were exclusively naval
and or air. Second, listing
the countries which have been invaded by the US
is a challenge in itself. For instance, in the
In the Spanish-American war,
the US invaded the territories of Cuba and the Philippines,
which were controlled by the Spanish.
Do we consider the invaded country Spain,
even though American troops were never in
Spain per se?
Or do we consider Cuba and the Philippines
as the invaded ones, even though the countries
were not established at the time?
I would argue the first one is the more correct option as,
at the time, it was Spanish territory
that was being invaded, even if not its European mainland.
Although this isn't the best example because both Cuba
and the Philippines were also invaded
on their own, but anyway.
We must also differentiate military conflicts
and wars from participation or aid in foreign
civil wars or coup d'etats,
even when they were organized by the US themselves.
For the sake of this video, I will leave both these cases out.
With that being said, let's provide
a visual list of invasions through this map.
I'm going to fill in the countries as I list them,
but of course they didn't invade
the entirety of the countries, keep that in mind.
And assuming the Spanish criteria,
so I'll be considering the invaded countries the ones
that controlled the territories at the time,
the US has in no particular order invaded
the following nations.
The British, Canada, Northern American natives,
the historic predecessors of modern Libya,
Tunis, Morocco, Algiers,
all of which were protectorates of the Ottomans, Mexico, Qing
China, the Joseon Dynasty and then Korea,
Germany both the Empire and the Third Reich, Italy, Spain,
the Philippines, Cuba, Nicaragua,
Haiti and the Dominican Republic, Austria, Japan, Laos, Cambodia
and Vietnam, Lebanon, Afghanistan and Iraq and also Grenada and Panama.
There's also other small
examples of US troops invading the land of other countries
but that aren't necessarily included in
specific conflict in tons of other countries
and regions where US troops have been or are
that we could fill in on this map
but I wanted to keep this exclusive to official invasions.
Again it's very confusing to categorize all of them
so this list might be incomplete or
slightly off in some cases.
If you notice any mistakes
or missing nations feel free to point them out in the comments.
So now that we've provided that overview let's look
at some specific examples that
show us the types of invasions these were,
why they happened, when and how.
Immediately at the start of the 19th century
was the first overseas invasions by the United
States.
The first Barbary war in 1801
which took place in the Ottoman protectorates of Tripolitana
as well as in Morocco.
The Ottoman protectorates of the Barbary states wanted
to charge protection fees so that US
ships wouldn't be raided by them.
They refused to pay and so went into war.
It was mostly a naval conflict
but the US did actually invade with a few hundred men
and this invasion was the turning point
of the conflict through the Battle of Derna when
a mercenary army recruited
and led by US Marines marched through the North African desert from
Alexandria in Egypt to the eastern port city
of Derna in Libya defeating the corsairs.
The Second Barbary War in 1815 also saw overseas invasion,
this time in Algiers for the same
reasons, but the invasion was literally just
at the end of the conflict, 99.9% of which
was naval and they also won this one.
The next invasion of a foreign country
was the Mexican-American War in 1846.
Following the American annexation of Texas,
which Mexico considered theirs, the two recently
independent North American nations went to war.
Not only did the US want Texas,
but also to follow the idea of Manifest Destiny and continue
expanding west into territories
that were at the time part of the Mexican Empire.
The US won and the territories of the current states
of California, Nevada, Utah, Arizona
and New Mexico were conquered.
Conflicts with Mexico existed various times
throughout history with many other examples
taking place like the Mexican border war of 1910,
the last major conflict fought on American
soil and somewhat connected to World War 1,
although not really, there were just some
specific Mexican revolutionary factions
that decided to attack border towns but since the
German Empire won in Mexico to attack the US,
they supported them apparently.
Having already been involved in invasions in North America
and Africa, Asia was next,
with the second opium war in China in 1856.
Siding with the UK and France,
the US fought and won against the Chinese.
This was a colonial war over the right to import opium to the country.
The US weren't a big part of the war
but offered aid to the UK and a Chinese garrison
at Canton shelled a US steamer leading
to the Battle of the Pearl River Forts where
the US launched an amphibious assault against
a series of forts in what is today Guangzhou,
China.
They returned to China in 1899 with the Boxer Rebellion.
This was an anti-colonial uprising
so all the colonial powers united against them and
the US was one of them, forming the Eight Nation Alliance.
The Boxers had the colonial legation quarter of Beijing surrounded
and so this 8 nation
army moved on to break the siege.
In this painting we can even see US troops climbing
the walls of Beijing and placing
an American flag on top of them.
There were also other small conflicts
in which US soldiers took place during these uprisings.
And after a few internal wars against the natives,
they were back to Asia in 1871 through
the US expedition to Korea against the Joseon Dynasty,
mostly taking place in the Gwanghwa
Island.
The reason for the presence of the American land forces
in Korea was to support an American
diplomatic delegation sent there and led by the US ambassador to China.
The Koreans didn't want a trade treaty
and requested the US not to go into their territory
with them ignoring the request
and so the Koreans attacked the ship that was in their
territorial waters.
In retaliation, about 650 Americans landed and captured several
forts culminating in the Battle of Ganghwa.
A news article from the time makes the argument
that it was the US ambassador's plan
to demonstrate American power over what he considered
to be a weaker nation.
Also, of course, having been fully involved in another Korean war
later in history in 1950,
fighting alongside the South and invading the North. A key part
and conflict within the Cold War placing North
and South Korea against each other, one supported
by the Soviet Union and China and the other by the US.
This war was unresolved and remained so up to today.
Next we have Germany which was invaded
by the US three times throughout its history.
The first was the Second Samoan Civil War in 1898 where the US,
UK and Germany were
fighting over who should control Samoa.
They ended up splitting it into an American and German colony,
the German one is now independent
Samoa.
Then World War I where they also invaded Austria-Hungary
and World War II where they also invaded Italy,
fighting through various other European territories
that were under the control of these nations
at the time.
A key invasion target of the US was also Spain,
although as we saw, not in its European mainland
as I pointed out on the map.
The Spanish-American War of 1898
was the final destruction of the Spanish colonial empire.
It began with US participation in the Cuban War of Independence
and then the Philippine
Revolution.
US won and Spain relinquished sovereignty over Cuba,
Puerto Rico, Guam and the Philippines
to the United States.
Following that war and the loss of these territories by Spain,
the US also invaded both of these
nations.
Although the Philippines war was immediately after
with the locals fighting for independence,
however the US won and the Philippines became
an unincorporated territory of the United
States while the conflict with Cuba
was only much later in history in 1961 with the Bay
Pig's invasion, a failed military invasion attempting
to overthrow their revolutionary
government. Moving past Mexico there
were also several other US interventions in Central America
and the Caribbean such as Nicaragua in 1912,
siding with the regime against revolutionary
forces to stop any other nation from building a Nicaraguan canal,
Haiti in 1915 with the landing
of 300 soldiers in the capital of Port-au-Prince
to take control of Haiti's political and financial
interests protecting American businesses there,
there's a series of US invasions and occupations
in Central American nations to secure
their own business interest known as the Banana Wars.
The Dominican Republic in 1916 following
a local revolution that wasn't friendly to the US
and leading to the establishment
of an American sponsored puppet government.
Grenada in 1983 was the same with the US
not accepting a revolutionary government
and invading to restore the previous one,
Panama in 1989 where the primary purpose was to depose
their de facto ruler, General Manuel Noriega
who was wanted by US authorities and Haiti again in
1994 to remove a military regime and restore the previous government.
At the end of the 20th
century several invasions in Southeast Asia also took place,
Vietnam in 55, Laos in 59 and Cambodia
in 67, all of these resulting in a catastrophic defeat
by the US in 1975. They were all a part
of the cold war too with the Soviet Union
and China supporting one side and the US the other.
US interventions had to do with wanting to stop
the spread of Soviet influence to the rest of
Asia. And finally the middle eastern area was time
and time again invaded by the US. Beginning with
the Lebanon crisis in 1958 when Lebanese president
requested US intervention to stop a political and
religious crisis it was part of the eisenhower doctrine
which aimed to provide assistance to
any middle eastern country that was being threatened
by armed aggression also seeking
to prevent the expansion of communism
into the region returning to lebanon in 1982 in a
multinational intervention to establish
a peacekeeping mission for the country's internal
conflict then they also invaded iraq first in 1990
and then again in 2004 the first being to stop
Iraq from annexing Kuwait
and the second due to false pretence of stopping the usage of
weapons of mass destruction in Afghanistan
also in 2001 for region stabilization purposes
arguably having very much the opposite effect.
So that is a brief overview of all
the times US soldiers have invaded the territory of
another country within the context of an official conflict,
attempting to provide an important
piece of context, that there
are far more US military interventions and wars that they
have taken part in, but that for this video
the point was only to consider nations that
have physically invaded on the ground with their own soldiers,
also considering the invaded
country, the nation in control of those invaded territories
at the time and not necessarily
the countries that exist there today,
leaving out naval and aerial only conflicts as well
as US participation in coups or internal conflicts of other nations,
providing a potentially
complete list of all these countries the US have invaded
and understanding in which parts
of the world that happened,
then going through a good number of specific examples of US invasions
and learning where, why and how those invasions happened,
which I believe provide us with
a good understanding of what events have triggered
them throughout history, either to expand
their territory, safeguard trade,
safeguard business interests or keep other powers from
expanding their spheres of influence in addition
to a few legitimate defenses against forces
of evil if you will.
And why, at least in modern times,
they seem to take part in more external conflicts than
almost any other nation in the world.
What is your opinion about these invasions?
Are any other big ones missing?
And which other countries have a history
of foreign invasions or being invaded?
