Absolutely! Just ask North Korea about the licking we gave them!! Oh, well, doesn't matter, we made up for that by crushing North Vietnam. Errrr, ummmm, nevermind.
The Baathists had a country, and do not have one any longer. The Taliban also had a country, and similarly no longer have one. Why do you focus on two mudhole conflicts from 50 years ago? If you want to "win" a war you have to at least know what that means going in.
There isn't a dictator on the planet that would square off against us now, because doing so means you != dictator any more. And being dictator is so much more fun than being dead.
That leaves the major powers. Anyone who thinks we're about to get into a shooting war with Russia and/or China over Syria is breathing a different air mixture than I am.
And note also that I am being really nice to Russia here by letting them slip into the "major power" category with China. Not really justified by any capability they currently possess.
