Sen. Barack Obama’s speech on terrorism, in which he asserted the right to pursue suspected al-Qaeda fighters in Pakistan , generated wide response from his fellow Democratic presidential contenders.

Sen. Chris Dodd said, “It is dangerous and irresponsible to leave even the impression the United States would needlessly and publicly provoke a nuclear power.” Bill Richardson stressed the importance of diplomacy before using military force in Pakistan. Sen. Joseph Biden added: “The last thing you want to do is telegraph to the folks in Pakistan that we are about to violate their sovereignty.”

But Sen. Hillary Clinton did not dismiss Obama’s proposal, saying, “If we had actionable intelligence that Osama bin Laden or other high-value targets were in Pakistan I would ensure that they were targeted and killed or captured.” John Edwards also seemed to echo Obama’s point, saying if the Pakistanis “can’t do the job, then we have to do it.”

Separately, Republican frontrunner Rudy Giuliani told Charlie Rose there is “not much” difference between himself and John McCain on the war in Iraq, and said he defines success in Iraq as “stability” (PDF) and “leaving behind an Iraq that will help us in the terrorist war against us.”
