Wha-what?

Empires are more trouble that they're worth.

Still, if you think about it, being the only ones with the atom bomb was a pretty advantageous position. There should be a "Wolfenstein" type game where the US used that leverage to take over the world.

You know, though, I can't really think of anyplace really nifty to take over. We already have Hawaii.

What do you mean by could and should? It pretty much has taken over the entire western world plus some. And the use of "us" and "we" is silly in a country with a population of 315 million diverse individual. U.S government =/=America or Americans.

Uhh there are U.S. military basically in every single country. They kind of did.

The Soviet Union handily outnumbered us, even if they were benefiting from lend-lease aid still at the very end of the war, they had more ground troops mobilized and more tanks. We could have beaten them (since we had untapped reserves in terms of draftable citizens and could have yet increased our war industrial capacity), but they had the immediate advantage on the ground, so it would have taken years and cost millions more lives.

America DID take over the world after WW2.

America has been THE profiteer of both world wars.

it almost seems like they've adopted a "world war strategy":
1. Initially, completely stay out of the conflict
2. Wait until the fighting parties have mutually ruined themselves
3. When all the key players are already mostly lying on the ground, find a reason for entering the war
4. No longer being faced with any significant military risistance, it's easy to force US will on pretty much all sides in the conflict
5. Exit the war as the big war profiteer, with hardly any losses
6. Fool later generations with endless amounts of Hollywood movies which give the impression that the US somehow was THE main force in the war, despite the US actually hardly even being involved (only about 0.7% of WW2 casualties were americans)

I don't think america had the resources or manpower to do it. Even if they could of, they wouldn't been able to hold onto the territories. I think america dropped the bombs on japan as an act of desperation and revenge.

If you count 5 or 6 soldiers as "us military", then yes, your close, but no, not every country has US military.

As a matter of fact, I know more Irish soldiers currently in the US training members of the US military than vice versa. It's pretty common for allies to share resources and have trainers go abroad.

Plot twist: They already did.

It's doubtful that America could have defeated the Soviet Union after WWII let alone the entire world. Additionally, it would have been impossible to retain the new territory. Conquering the planet through force can never be achieved, hence why it has never happened.
