I keep seeing the phrase "Israel has a right to exist" thrown around a lot of late, and it's a new meme that is grounded in nothing.
No nation "has a right to exist".
It's a nonsense statement with no international law or obligations to back it up.
If nations "have a right to exist", then countries like East Germany, Yugoslavia, Czechoslovakia, the list goes on, would all have been forced to remain a thing.
This is a deliberate distortion, and replacement, of the right to self-determination
