Just before World War I, there were a number of terrorist attacks on the United States forces in the Philippines, by Muslim extremists. General Pershing captured 50 terrorists, and had them tied to posts for execution. He had his is men slaughter two pigs, in front of the horrified terrorists

The soldiers soaked their bullets in the pig's blood, and proceeded to execute 49 of the terrorists by firing squad. The soldiers dug a big hole, dumped in the terrorist's bodies, and covered them in pig blood, entrails, etc. They let the 50th man go.

And for the next 42 years, there was not a single Muslim extremist attack anywhere in the world.
