The reason that WW3 or WW4 isn't coming any time soon is because there is no credible armed force aligned against the U.S.Forget the wild-eyed hype about China, it has only 18 servicable ICBM's and its main nuclear enemies are India and Taiwan. Forget Russia, as Putin has clearly sided with the U.S. against Islamic terrorists in Chechnya.
As it stands today, no enemy of America can seize and maintain space superiority, air superiority, or naval superiority. Only in the etheral world of computer wars and in the world of the grunt soldier can any coalition of forces credibly oppose the same U.S. forces, and without space, air, and sea superiority, they literally stand no chance against us.
These conditions aren't ripe for a new world war; they are ripe for complete disaster to befall on anyone who opposes the U.S. militarily.
Our economic, technological, and military superiority is more than a generation ahead of the closest potential combination of adversaries. Consider that China has still not managed to orbit its first man around the Earth, something that the U.S. did more than 40 years ago, for instance. In the Middle-East, such technological feats are even less plausible.
What the Islamic Revolution had going for it was unamity of opinion. That solid block of faithful believers made for powerful political statements and potent propaganda.
Their mistake, however, was in digressing from their strong suits above into our strong suits of economic, technological, and military warfare.
But the hilarious part is that they are too macho and too unclever to back down from their current path.
So the Middle-East wants war?!
So be it! Their masses of soldiers can witness firsthand the death and utter destruction that our lowly conventional military forces are capable of delivering at will from space, the air, the sea, and even on the ground.
And should we ever decide to escalate any particular conflict, our non-conventional forces pack a power that no other coalition of nations can hope to equal.
So are we headed straight for a new World War? Not a chance. There is simply no opposition capable of making a real fight of any conflict against us.
