The US is a nation more or less on one content, not an Empire that covers a system of multiple planets. There's going to be a difference between numbers. I'll take a gander and say that most nations here will have much higher numbers of troops than >1% considering they have a system and subsequently a galaxy to watch over is the Super Space Consul Union of Diplomacy and Rainbows sends UN-esque peacekeepers to places.
