The "Bush Doctrine of "pre-emptive" war - that is, removing a threat before it strikes at America...." is a doctrine we've seen before, practiced by leaders such as Adolf Hitler, Benito Mussolini, and General Tojo.

It's a doctrine that works very well as long as you don't arouse foreign armed forces that are too strong for your own military forces to handle.

It's also a doctrine that will get you arrested and tried for assault and first degree murder if you happen to be a private person, and not a politician. Why? Because is IS assault and first degree murder, premeditated and then carried out.

Try it on your neighbour (who you say is planning to kill you) and see what happens. You will be arrested and tried. So should Bush and Cheney be arrested and tried, in an international court.
