Good point.
I also know it is going to be hard to convince Israel to join a peace treaty and not wipe out Hamas. Israel has repeatedly signed peace treaties and given up land and every single time, it has hurt them in the longterm because their enemies are only interested in the complete destruction of the Jews. When groups like Hamas do a peace treaty, it is for the sole purpose of letting them rebuild and get resituated to attack Israel again.
It blows my mind (it shouldn't at this point) that Hamas attacks Israel, Kills more than a thousand civilians, including women and children, kidnaps others, and then when Israel retaliates, Israel is told they need to negotiate. What ever happened to "no negotiation with terrorists" because it just causes more terrorism?
Why do you think Hamas wants to destroy Israel?
At this point, both sides are at fault. Stopping the killing would be a good thing. That's, unfortunately, not likely, though.
