Condoleezza Rice says U.S. is safer today than it was on 9/11

The U.S. is safer today than it was 20 years ago, but it's not out of the woods, Condoleezza Rice said on the eve of the anniversary of the 9/11 terror attacks. 

"We are safer than we were on September 11, 2001, but we're not yet safe," Rice told "CBS Evening News" anchor and managing editor Norah O'Donnell on Friday.  "We gave ourselves 20 years of peace when there was not another attack of anything like that scale where we developed intelligence assets on the ground," she continued. "But of course, it sad that on this day, the Taliban is back in Afghanistan and in control. I don't think it had to be that way, but it's bittersweet."
