Cuba and Israel: Get Them To Fight?
El Salvador and Costa Rica have ended their economic embargo/sanctions against Cuba. That means America is the only country left on Earth to have such a position.
In the United Nations, only one country on Earth stands up for Israel, and that is America.
For over a century Cubans in America have been agitating for America to take an active interest in that country (see Grover Cleveland's 1896(?) State of the Union address for an example). This interest, at all times, comes with a cost. Much the same can be said for Israelis in America, except the timeframe is only half as long.
Cubans and Israelis are fighting over scarce resources. If we get them to fight it out, they can become each other's worst enemies, saving rational people the effort of having to point out how stupid America is being in both instances.
Cubans Against Israel is a real group that I just made up that thinks U.S. Foreign Policy towards Israel is shameful, and Israelis Against the Cuban Embargo is another radical fringe element (which I just made up) who thinks economic sanctions against the Castro regime are getting America nowhere, and so the effort shouldn't be wasted.
