Like, it's worth noting that the core of the nationalist and unionist terrorists still live in Ireland and engage in a bunch of criminality. These organizations don't disband, they just die off/become politicians.
The big problem with Israel making peace is that it appears a solid majority don't want that, which depresses the hell out of me.
There are many peace activists on both sides but also a lot of fatigue and disillusionment. Don't let that get you down too. I think once the dust settles things could change. The pendulum always swings to the other side, we just need patience and to set an environment receptive for that. If Trump wins this election things will probably get much worse before they get better. But I think that they will get better even in that worst case scenario.
If it were true that violence breeds violence then Jews would have blown up post war Germany with suicide vests. It was still filled with Nazis and their collaborators.
Hamas is a different story, there's no amount of negotiations or compromise that will placate a fanatic. They will probably keep doing these things forever just like Isis didn't fully go away. But once the leadership got cut down Isis found it much harder to pull off the same level of terror.
I agree that this needs to be a dual motion. Young frustrated people are kindle for these organizations and this won't work without a peace process that would give hope to the people. That's why I don't have any faith in the current Israeli government. I hope it can be replaced so there would be a parallel process that would help rebuild and pave a way for peace again.
