There have been dozens of US military interventions around the globe since America was founded.
It started even before we were fully independent – with an invasion of what's now Canada in 1775, and a raid on the Bahamas in 1776.
But when it comes to sending troops to foreign lands, we've got nothing on the British.
A new book suggests Britain gets the dubious distinction of having invaded more countries than any other.
It's called "All the Countries We've Ever Invaded: And the Few We Never Got Round To". It's by popular historian, Stuart Laycock.
The book claims there are only 22 nations in the world that have never suffered British military attack.
As The World's resident history buff, I think, however, Britain has invaded even more countries.
Sweden leaps to mind, as an obvious omission. After all, who can forget the Gothenburg expedition of 1808?
That was when British forces were sent to bully the king of Sweden into opposing Britain's enemy, Napoleon, Emperor of the French.
Then there the possibly of Guatemala. I'm pretty sure that when some British logwood cutters were trying to set the colony which became modern Belize, they raided the coast of Guatemala next door.
Here's Stuart Laycock's list of the 22 nations never invaded by Britain:
Central African Republic
Congo (Republic of)
Sao Tome and Principe
