I can provide the info in context, dragonfly.
"I understand that President Musharraf has his own challenges. But let me make this clear. There are terrorists holed up in those mountains who murdered 3,000 Americans. They are plotting to strike again. It was a terrible mistake to fail to act when we had a chance to take out an al Qaeda leadership meeting in 2005. If we have actionable intelligence about high-value terrorist targets and President Musharraf won’t act, we will."
Further,
"I will not hesitate to use military force to take out terrorists who pose a direct threat to America. This requires a broader set of capabilities, as outlined in the Army and Marine Corps’s new counter-insurgency manual. I will ensure that our military becomes more stealth, agile, and lethal in its ability to capture or kill terrorists. We need to recruit, train, and equip our armed forces to better target terrorists, and to help foreign militaries to do the same."

As one can see, Senator Obama did not say anything about bombing Pakistan. He referred to special forces-type operations - small, quick, and stealthy -
against al Qaeda, not Pakistan.
