he former commander of U.S. special forces in Afghanistan and Iraq admitted that strategic blunders by the Bush administration had led to the rise of Islamic State militants.

Retired Lt. Gen. Michael Flynn told the German newspaper Der Spiegel that Americans allowed their anger of the Sept. 11, 2001, terrorist attacks to lead them into disastrous military policies that failed to address the root causes of terrorism — and actually helped create new and more brutal terrorists.

The misunderstanding was so great that Abu Bakr al-Baghdadi, who now heads ISIS, was freed in 2004 from a military prison after a U.S. military commission cleared him as harmless.

"We were too dumb," Flynn said. "We didn't understand who we had there at that moment. When 9/11 occurred, all the emotions took over, and our response was, 'Where did those bastards come from? Let's go kill them. Let's go get them.' Instead of asking why they attacked us, we asked where they came from. Then we strategically marched in the wrong direction."

The U.S. invaded Iraq after administration officials — including George W. Bush, Dick Cheney and Colin Powell — presented false intelligence about Saddam Hussein's weapons of mass destruction and alleged links to al-Qaeda.

"First we went to Afghanistan, where al-Qaeda was based, then we went to Iraq," Flynn said. "Instead of asking ourselves why the phenomenon of terror occurred, we were looking for locations. This is a major lesson we must learn in order not to make the same mistakes again."
