Who are we to judge Israel. Just as our country has done they have laid claim to a piece of land and they are defending it. And maybe going to expand it. We did the same. And killed and displaced a bunch of people in the process.
And unlike us Europeans they had prior claim to the land that they reclaimed.
Military victory has settled the matter.
Personally I think they have shown a lot of restraint.
Is this what you are referring to when you say I endorse genocide?
