There are several generations of Israelis born Israelis. They don't have anywhere they are from to return to.
I agree there is no realistic solution without genocide in sight, but that is not an excuse to support more genocide.
The isrealis need to be condemned and isolated from international support. After we accomplish that, we can re evaluate. They might not be so bloodthirsty if the US and other countries weren't so ride or die for the IDF.
