Bush needs all this to hapen before October, so he can use the flag waving American propaganda machine the keep his rubberstamp Congress and hoping that the television-watchers will give it to him. Then, he can relax, as he knows once he keeps his congress, he can persuade them to protect his ass from any danger of impeachment for any number of crimes he has committed, and possibly save him from being tried as the war criminal he is.
Before that can happen, he needs a terrorist attack, and what do you know, he gets one. Or at least the threat of one. That's all it takes for the television-watchers' paranoia to kick in and he can violate any law there is, as long as he justifies it by using national security and invoking 9/11, although that last one is just about used up.
Bush' speech will draw distinctions between countries that want peace, such as most of the countries in the region, and those extremists who want to spread terror and violence, such as the US and Israel.
"The world must stand up for peace."
They do, Mr. President. That's why they won't stand for you.
