I thought that after the President had his meeting with Mideast Leaders in Saudi Arabia last year, he might develop a NATO-like organization among the Sunni nations with the Saudi and Egyptian armies being the nucleus. The US would support and train but they would do the fighting. Personally, I like the idea.
Saudis can’t fight. They pay Sudanese to fight for them and both the Sudanese & Saudis get slaughtered in Yemen.
