英语文摘:Obama, Romney Look to November Showdown

President Barack Obama’s surprise trip to Afghanistan on the first anniversary of the death of Osama bin Laden is the latest indication that foreign policy and national security issues will matter this election year, even if most political analysts predict that the economy will be the central issue in the U.S. presidential campaign. 

While in Afghanistan, the president signed a long-term security agreement with Afghan President Hamid Karzai and met with U.S. troops at Bagram Air Field. And, in a televised address, Obama spoke about winding down the U.S. military commitment in Afghanistan.

"I will not keep Americans in harm's way a single day longer than is absolutely required for our national security," the president said.  "But we must finish the job we started in Afghanistan and end this war responsibly."

To highlight the one-year anniversary of bin Laden's death, the Obama presidential campaign released a video recalling the decision to go after the al-Qaida leader and the tense moments that followed.

“He took the harder and the more honorable path,” former U.S. President Bill Clinton said in the video.

The Obama campaign also raised the issue of whether the president's expected Republican opponent in November, Mitt Romney, would have approved the bin Laden raid - based on a 2007 comment he made questioning the resources devoted to the manhunt.
