Only one state solution is possible. Let Palestinians back to their homes, with jews and muslims side by side. But Israel will never ever allow “gentiles” to be amongst them. Zionist Israel is a racist entity and a threat to global peace
A one-state solution is not the answer either, as it will cause a demographic crisis for Israel. According to their law passed under the current Prime Minister, Israel is meant to be solely a Jewish-majority state by its very nature.
The Palestinians should be able to relocate to other parts of the world. Currently, it seems that no one, not even their fellow Arabs, wants them. I would even go as far as to say that they have been used by surrounding Arab nations as a buffer. They basically sacrificed their own extended Arab members to the enemy.
