The US needs to start imagining something else. It's hard to think of the last war that the US won.
Do they need to win though? Losing wars seems to have worked out well so far, at least for the people who benefit from it
And yet they rule the world. Whether or not US won any specific war seems academic when (up until recently) they were clearly winning the game.
On a technicality, America has won every war it has declared to be a war.
