What Obama did was anti-American in that he assassinated a criminal perpetrator without putting him on trial first. "Habeas Corpus" is in the U.S. DNA and in the Constitution.

I'm certain that most of the world would have found bin Laden guilty of murder had there been a trial.

Also, not every member of the Taleban supports Al Quaeda.

One thing is certain, the Afghan Security Force is ultimately being trained to kill American soldiers.

The US is naively unaware of the quagmire that their incursion into Afghanistan has caused. The evidence is shown by the role of the mujahadeen in fighting the Soviets in Afghanistan.

Why did the US support the bin Laden family (as well as Usama?) Was it "oil"?
