I dunno, sounds made up, especially the rationalization about “eating less pork in hot climates” (like they had never heard of cured meats — ham, bacon, etc.).
Anyone, as in modern times, who would want to even nominally honor the right to choose Islamic beliefs, as long as they are not carried into violence, would also be loath to do this.
A “solution” like this sounds unstable, or it would have grown to encompass the world. Also it underestimates the ability of imams to produce theological rationalization. Like somehow if you die spectacularly enough, this then would transcend the physical presence of any porcine remains.
Nothing but actual, genuine evangelization will work against what is a spiritually driven menace. Physical death of their hosts will not send the demons to hell. Jesus Christ, however, will.
Well, the article does state that General Pershing wrote about the burial of Mohamedans with pig offal in his autobiography.
That would be easily verifiable.
And don't forget that the time of General Pershing and the burial of Mohamedans with pig offal occurred over 100 years ago.
Everything was much different then - more basic to say the least.
Logistics, values, technology, food preservation, rules of engagement, budgets, the government, the media - everything.
There was no political correctness and wars were fought with the objective of killing the enemy and winning the conflict - not to win the hearts and minds of the enemy.
