"The first step must be to get off the wrong battlefield in Iraq and take the fight to the terrorists in Afghanistan and Pakistan."

Said Obama. "There are terrorists holed up in those mountains... If we have actionable intelligence about high-value terrorist targets and President Musharraf won't act, we will."

This flung open a door to criticism:

"It is dangerous and irresponsible to leave even the impression the United States would needlessly and publicly provoke a nuclear power," Sen. Christopher J. Dodd (Conn.) said in a statement.

New Mexico Gov. Bill Richardson, in a telephone interview, said that Obama's threat, if acted upon, could inflame the entire Muslim world. "My international experience tells me that we should address this issue with tough diplomacy first with Musharraf and then leave the military option as a last resort," he said.

Former senator John Edwards (N.C.) said in a statement that he would first apply "maximum diplomatic and economic pressure on states like Pakistan and Saudi Arabia" to do their utmost to combat the spread of terrorism. He also challenged both Obama and Clinton to block a proposed U.S. arms deal with Saudi Arabia.

Sen. Joseph R. Biden Jr. (Del.), chairman of the Foreign Relations Committee, called Obama's threat misguided. "The way to deal with it is not to announce it, but to do it," Biden said at the National Press Club. "The last thing you want to do is telegraph to the folks in Pakistan that we are about to violate their sovereignty."

Nothing from Hillary yet.

So has Obama convinced you he's a tough guy -- a smarter tough guy?
