Well Vladimir,

It isn't nice to respond to ignorance with more ignorance.

The Americans won their wars against the Mexicans and gained alot of terrory that way and they won the Spanish-American war again winning alot of land and resources.

The WW2 Pacific battle against the Japanese was indeed largely a US effort and so would qualify as an US victory. The European WW2 theater was indeed significantly different in the fact that the Russians actually won that war and not the Western allies. So we can't really coin that as a US victory as you also suggest.

War of 1812 was a stalemate I believe against the Canadians and Brits, but I would need to check that.

All the other victories by the US army were all against much much much weaker enemies (like Grenada, Panama) and while technically qualifying as victories are better not regarded that way. As soon as the enemy was just a little more then a push over the US forces struggled, examples Cuba (stalemate), Korea (stalemate) and Vietnam (loss)

So indeed the US did win a couple of their wars. No need to pretend otherwise.
