"He said U.S. troops are working to secure polling places so the elections can go forward and Afghans can choose their own future.
Attaining that peaceful future "will not be quick, nor easy," Obama said.
He said the United States still has a deep interest in the long-term outcome. "So this is not only a war worth fighting. ... This is fundamental to the defense of our people," he said.
He told the veterans that the U.S. didn't choose to fight in Afghanistan but was forced to invade that country to stop future Sept. 11-style attacks." (emphasis added)

So President Obama embraces the Bush Doctrine. Not surprising that he assumes this doctrine to be his and doesn't cite Bush as the originator of it.

Where are the main stream media press on this?
