World of difference.
Russia invades countries to steal their resources and annex their lands. And they bomb civilian residences and civilian infrastructure in the process, and kill many citizens in the areas they capture.
The US doesn't seek to annex any areas or take their resources, even when we ought to because the wars cost us money. We invade because a state has become a terror sponsor like Afghanistan or because they invaded another country like Iraq did Kuwait.
Then how did we get New Mexico?
