Really?
In roughly 1 year starting in April 1917, the US and her allies overwhelmed the static western front and overcame the world's most powerful army.
In roughly 3-1/2 years starting in December 1941, the US and our allies liberated about 1/4 of the surface of the earth, wiped out the world's largest navy and second largest army, and replaced all the enemy governments with those friendly to our side. In the few months after that, several dozen of the worst surviving enemy criminals were tried, convicted and punished.
The Bush-Bush war against Iraq is now about about 15 years old, one small country has been liberated, our capital and our largest city have been attacked at high loss of innocent life, and the enemy country is nowhere near pacified, nor is there a stable friendly governamnet there.
Oh, you were being sarcastic. Never mind.
