"But if the threat of anti-semitism is the argument for bombing, then it can by definition never stop."
A group like the Westboro Baptist Church shouting Antisemitic shit (and all other sorts of bile towards other races) is no reason to bomb...they have no weapons, they can't hurt anyone physically, and they're not violating anyone's national sovereignty.
Once you 1. Acquire thousands of rockets and enough military-grade guns to field a guerrilla army, 2. Broadcast to millions of others that it's God's will to exterminate the Jews, and 3. Violate Israeli national sovereignty by digging tunnel after reinforced tunnel miles into Israel (no matter how you slice it, that IS a violation of their national sovereignty and that IS an act of war)...
Then the game changes.
"the main threat to the existence of Israel and the people living on both sides, are crazy right-wing groups that still deny people a right to exist, a right to their own self-determination, denies the right to a state."
I agree that right wing groups on both sides are the problem...
But I also think they keep one another in office. Hamas attacking Israel and Israel responding creates a culture where that far-right wing becomes more favorable to the people than a more liberal approach towards an enemy firing at you, or making threats of genocide, or putting up checkpoints, or tunneling into your territory.
That's again why I say Hamas is the problem and that, if the Palestinians really want to win this and achieve their aims, Hamas has to go...because not only does violence beget violence, but it keeps the party least likely to hear the Palestinians out and least likely to ever offer them a better deal in office.
I again point to MLK vs. Malcolm X here...
It wasn't the latter that convinced Congress and JFK/LBJ and millions of white Americans do something and give the Civil Rights Movement the mainstream power it needed to succeed...Malcolm X's violent approach towards whites didn't win over that white group and make them feel like this really WAS one side being unfairly discriminated against.
Think of it this way:
With Malcolm X/Hamas, the South/Israeli Right could/can always say "Look, whites attack blacks, but blacks attack whites, see BOTH sides are at fault...that's why we need segregation," or "Look, we attack them, they attack us, see, BOTH sides are at fault...that's why we need to blockade Gaza."
Hamas is sadly fulfilling that role, and thereby allowing even someone like you, TheMinisterOfWar, you say they're equal partners in this crime, rather than take the Palestinian side outright.
As a (presumably) white person, who would've won you over in the 1960s--a black militant advocating armed fighting between whites and blacks, or a black preacher saying what matters isn't the content of one's skin but the quality of their character?
I don't know about you, but speeches do more to win me over than do bullets...or, in the case of Hamas, rockets, tunnels, and promises of genocide.
