It's easier to say "I will clsoe GITMO in the 1st year of my presidency" than actually doing the deed. IMHO, President Obama had to have been briefed on the fact that "other" countries wouldn't take these GITMO folks before he won the election. Hell, we all knew it when Bush was in office.
He and his boob AG Holder wanted to "have a trial" in New York for show. But that didn't pan out either. So now he's stuck just like Bush was stuck. They are people who no one wants on their soil.
