Yeah, pretty much. The president has enormous power, and that power is even greater outside the country's borders. Especially because of things like the "Authorization to Use Military Force" which gives him pretty much carte blanche to "fight terrorism" anytime and anywhere he likes.

There's also this general process by which the president historically just does what he wants, and the rest of the government shrugs its shoulders and rolls over, and thus his office essentially just has that de facto power, no matter what the constitution or other laws say: Renegade Cut: No More Presidents.

The U.S. president is more powerful than any empire in the world has ever been, is pretty much a king, and basically does what he wants. Liberals often make excuses about how his hands are tied. It would be great if that were the case, but it's really, really not.
