Nothing is more dangerous than a naïve appeaser, other than a naïve appeaser who erratically takes rash steps in order to look tougher than he really is. Terrible, tragic events are set in motion by such threats of bluster. Tyrants are not deterred, and when the bluff is called, the erratic faux tough-guy gets into situations he is unprepared to resolve.

Democratic presidential candidate Barack Obama said Wednesday that he would possibly send troops into Pakistan to hunt down terrorists, an attempt to show strength when his chief rival has described his foreign policy skills as naive.

The Illinois senator warned Pakistani President Gen. Pervez Musharraf that he must do more to shut down terrorist operations in his country and evict foreign fighters under an Obama presidency, or Pakistan will risk a U.S. troop invasion and losing hundreds of millions of dollars in U.S. military aid.

"Let me make this clear," Obama said in a speech prepared for delivery at the Woodrow Wilson International Center for Scholars. "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-Qaida leadership meeting in 2005. If we have actionable intelligence about high-value terrorist targets and President Musharraf won't act, we will."
