Good idea. But the Saudis and their pals much prefer to spend the money building more and more terrorist training schools and camps all around the world wherever they can. Plus mosques specially staffed with their own extremely radicalized Wahhabi islamoNazi - ish “ clerics “.
This plan would give Arabs that opportunity.
Also, knowing how much money the world spends on 'peace talks' in the region - we'd all save money by 'chipping in' and buy Palestinians their own country. Kerry and dems love giving money away - and this plan might actually be an 'investment'...
Jordan gives up some useless land on one side of their country that they get back from other neighboring Arab States on the other side...Arabs donate land - we give cash... The Arab world 'pays' Jordon - and we all live in peace. Or we discover that Arabs don't care about peace, Palestinians, or anything except stoking the fires of their hatred. It'd be interesting to find out.
