The Moros in Mindanao were fanatical. Still are. Pershing whipped them so bad they didn't rise again for 40 years. In the case of the Pashtuns, most are not suicidally fanatic Islamic jihadis, but most ARE really into revenge and hospitality and other tenets of the Pathan Code, which the Arab al Qaeda jihadis manipulate to their benefit.
The stragedy that Gen. Blackjack Pershing used was to send in the "pigs". The Moros gave up enmasse. This stragedy should be used in Iraq.
Good point on the Moros. Don't forget, however, that he used a "guns and butter" approach, and while he was crushing the enemy forces, Americans poured into the Philippines to build hospitals, streets, schools, and so on. Those "behind the scenes" troops and civilians had a powerful impact on the outcome of the Filipino Insurrection/Moro Wars.
