about the United Nations -- calling it "useless," and "a waste of taxpayer money" -- and blasting President Obama for not having already launched a full-scale war in Syria:

“The president apparently wants to have a kind of cosmetic strike, launch a few missiles and then say, ‘Well, we responded,’ ” Senator John McCain, Mr. Obama’s Republican opponent in 2008 and a longtime advocate of stronger action in Syria, said on NBC’s “The Tonight Show” on Friday night. “This is the same president that, two years ago, said Bashar Assad had to go. It’s also the president that said there would be a red line if they used chemical weapons. Maybe that red line was written in disappearing ink.”
