I always thought, when one country moves troops into another and takes over, that's an invasion. Regardless of whether it sets up a new government to run the country invaded. Regardless of who recognized the existing government. Or whether the country had a govenment. Or whether factions in the country favored the invasion. Or whether the invasion was a good thing or a bad thing. And above all, regardless of whether the Royal Marines are permitted to go off base.

Am I wrong?
