The United States military gets around. There are the countries with which it's gone to war – Iraq, Germany, and Japan. There are countries it helps protect – Turkey, Poland, and Bahrain. And there are countries most people don't even know that America sends troops to, like Thailand, Pakistan, and Antarctica. There are so many countries. In fact, there are only three countries in the world America hasn't invaded or have never seen a U.S. military presence: Andorra, Bhutan, and Liechtenstein.
American historian Christopher Kelly and British historian Stuart Laycock are the authors of "America Invades: How We've Invaded Or Been Militarily Involved With Almost Every Country on Earth." They define "invasion" as "an armed attack or intervention in a country by American forces."
Americans have been invading other countries since before America was a thing, as early as 1741, when the North American battleground for the War of Austrian Succession was called King George's War – one of the French and Indian Wars. That's a lot of wars.
According to Kelly and Laycock's book, the United States has invaded or fought in 84 of the 193 countries recognized by the United Nations and has been militarily involved with 191 of 193 – a staggering 98 percent. The authors pose mixed, apolitical ideas. Without America's worldwide military involvement, the U.S. would be smaller with less clout, and Mexico would be bigger, with more clout. American invasions checked the spread of totalitarianism in the 20th Century, and without such opposition, the spread could have been much worse.
Finally, despite the image of an "imperial" United States, *only* America can meet some of the transnational challenges faced by the world in the 21st Century.
Here are the only 3 countries America hasn't invaded
The tiny landlocked country of Andorra is a parliamentary democratic diarchy, run by two princes — which should be easy for Gen X-ers to remember.
Andorra has no standing army. Instead, they have a militia ready to take arms if necessary. Since they are landlocked, they have no navy. Still, they were the longest combatant of World War I, technically remaining at war with Germany until 1958.
Bhutan is also landlocked between two countries. Unlike Andorra, the countries surrounding Bhutan would probably roll over the tiny country in the event of a war. Bhutan's 16,000-strong army is trained by the Indian army, and the country has no navy or air force.
Bhutan is a constitutional monarchy with some Buddism sprinkled in – which meant the expulsion of 1/5th of its population of ethnic Nepali Hindus who would not conform.
This little principality is locked between Austria and Switzerland. At just 62 square miles, one of the reasons America has never been here is that they might have trouble finding it on a map, just like two U.S. Marines famously did. They missed Liechtenstein and hit Germany instead.
Liechtenstein doesn't really need the help. They're a constitutional monarchy with a democratically-elected legislature, low taxes, high employment, and a 100 percent literacy rate.
