This and this are two links explaining US foreign aid. Yes, military aid is included in these figures. If you want it straight from the US government, click here. If you don't feel like reading all of it, skip to page 74.
OK, the US sometimes helps people without getting direct benefits out of it but not most of the time.
How do you hold Lincoln to be a criminal for the American Civil War?
The southern states must have had a right to leave the United States, just like the United States had a right to be independent of Britain. But Lincoln provoked the war to force them back into the union.
Later guys, like Wilson, didn't even pretend to care about what the constitution said.
Incidentally, the US got involved militarily in WWII because we were attacked by Japan and had war declared on us by Germany. All nations act according to their interests.
But the US wouldn't have cared if Adolf had just enslaved continental Europe and there had been no Japanese attack and no German declaration of war.
I notice that you vilify absolutely everything that the US has done over the past century or so without making any room for the good that has been done. You also don't seem to hold other nations to these standards. The US government may be a tyrannical, Constitution-breaking den of thieves, but it's not as black and white as you claim.
As an anarchist I don't think that
any state is even legitimate, but the US has mostly done things out of its own interest, yes. This thing with giving other countries "democracy" has been used for 100 years now.
