A while back there was a thread in post-1900 forum asking what POD would result in Israel having better relations with Arab countries. One of the responses was for Israelis to as early as possible ethnically cleanse (through deporting, not genociding) ALL the Palestinians. The reasoning was that although it would be a “short-term” PR nightmare, it would avoid the constant and simmering conflict in the region that the Arab leaders could use to rally their populations against Israel, leading to normalized relations within decades.
The author of this opinion pointed to how the USA dealt with the Indian populations and said “You don’t have Indians shooting SCUDS at American cities now”.
This got me thinking: (regardless of what you think about the Israeli-Palestinian conflict) is there any way to prolong the “Indian Wars” and have a anti-USA Indian insurgency well into the 20th century? Bonus points if you find a way for Indian rebels (NOTE: they have to be a guerrilla force) to fire ATL-SCUD missiles into a USA city at least once.
