In July 2008, CNN's Larry King interviewed then-presidential candidate John McCain. The host asked the Republican senator, "If you were president and knew that bin Laden was in Pakistan, you know where, would you have U.S. forces go in after him?"
McCain said he would not.
"Larry, I'm not going to go there and here's why: because Pakistan is a sovereign nation."

Mitt Romney tried a similar tack during a nationally televised GOP debate:
"Obama went from going to sit down to tea with our enemies, but then he's going to bomb our allies. I mean, he's gone from Jane Fonda to Dr. Strangelove in one week."
