Regarding you laugh about Obama "wanting to invade Pakistan"... your man Bush has suggested the same thing:

NEW YORK (CNN) -- President Bush said Wednesday he would order U.S. forces to go after Osama bin Laden inside Pakistan if he received good intelligence on the fugitive al Qaeda leader's location.

"Absolutely," Bush told CNN's Wolf Blitzer in an interview scheduled for air Wednesday afternoon. Although Pakistan has said it won't allow U.S. troops to operate within its territory, "We would take the action necessary to bring him to justice."

But Pakistan's president, Gen. Pervez Musharraf, told reporters at the United Nations that his government would oppose any U.S. action in its territory.

"We wouldn't like to allow that at all. We will do it ourselves," he said.

In fact, we've already attacked targets within Pakistani territory:

A January airstrike on suspected al Qaeda figures on the Pakistani side of the border provoked protests by tens of thousands of Pakistanis and complaints by Prime Minister Shaukat Aziz, who said U.S. officials launched the attack without consulting his government. (Posted 3:49 p.m.)

For the record, this is what Barack said:

"If we have actionable intelligence about high-value terrorist targets and President Musharraf won't act, we will."

Obviously talking about Special Ops type endeavors, not some general invasion by our troops.

So I suppose that if we knew where Bin Laden or Zawahiri was located on the Pakistani side of the uncontrolled Afghanistan-Pakistan border, we should just do nothing if Pakistan did not take action?  Because that's the kind of targeted operation Obama was talking about.
