It really is in everyone’s best interest to have both Israel and Palestine as sovereign states with normal diplomatic relations between them. It would make people in both countries safer. It would make the region more stable. And it would eliminate a lot of uncertainty that makes the world tremble every time tensions flare.
But both Hamas and Netanyahu need to have an “other” to attack to keep their own power secure, and so millions suffer while a few in power benefit.
And the great irony is that there would be UN peacekeepers on the ground right now if this were happening elsewhere in the world. Not because people care more about elsewhere, but because they care less.
