So why hasn't Israel just been granting all Palestinians citizenship?

It's not really about coexistence, is it? Rather than existing together, it's at best about existing separately.

>Peace for Hamas is eradicating all the Jews.

Which is a perfectly natural position considering the historic relationship here.

Why? First of all, we tried to give citizenship to Palestinians in East Jerusalem, they refuse.

Second, are you suggesting to annex Gaza and th West Bank, and giving them citizenship? That means the come election, Hamas would be the biggest party in the Knesset, revoke all democratic rights, and create a sharia state. That will be the end of the only democracy in the Middle East.
