Ok, I know the Israelis won't go for this, but...Whadaya think?
1) Forgive all Mexican debts to US, in exchange for Baja California.
2) Move Israel to Baja California, or Nuevo Israel. Pay to move Wailing Wall to Nuevo Israel.
Eh? What do you think? Eases Mexico/US tensions. Pulls the Jihadists excuses for terror, and they have to figure out the Palestinian problem.
Win/win? I think so. The Israelis have long known how to turn a desert into a prosperous nation. Jihadists have to come up with a new and transparent excuse for their acts. And we wind up with a prosperous, industrious, safe and secure neighbor!
