Russia just said that if the United States jumps into the war in Syria, it'll end up being the Third World War! Now, there's no reason to believe that Russia can't make good on that threat. This is a superpower, even though the United States likes to engage in the make-believe that they lost that coveted title when the Soviet Union collapsed. I fear that the threat of another world war might be too good an offer for the United States government to pass up. "What?! We could have another world war?! Why, that would be swell! We haven't gone out and had a world war in a long time! It's always been having to settle for wars that end up in cease-fires and we're hungry for another war an hour later! Gosh, we haven't had a world war since 1945! Honey, do you know where my good tie is? I want to look nice! I'll call the UN and make reservations."
