Well it kinda seems like all this unrest in the middle east was leading up to something. I wouldn't be surprised if all these protests in middle eastern countries were caused by the US and Israel to disrupt and kinda get a foothold in the area, knowing it was leading to something bigger.
I think we all know its coming, but why? What exactly is there to gain from having a all out war in the middle east possibly triggering something like WW3.
Our economy is shit, but thats probably one reason we would go to war. If we couldn't pay our bills we might as well use our huge military power to push people around till we get what we want.
