that's assuming all these concerned parties actually want a solution and not just to vilify Israel
For this statement to be valid it would be required that the concerned parties are equal. In the case of the Israel and Palestine there is a power imbalance. On one hand there is the zionist settler colonial power of Israel that is one of the strongest military forces in the world. One the other hand you have Palestine that is not even recognized as a country by the colonizers and instead of borders the colonizer has raised a wall controlling amongst other things the few entrances.
Calling out Israel for its settler colonial policies is no synonym to vilifying it.
