That's part of why they're acting this way. Security fears. I'm telling you, the median Israeli isn't motivated by bloodlust or a desire for land, they're motivated by a high level of fear that they will one day be killed by Hamas/Hezbollah/etc. That fear causes them to demand complete "security control" of the West Bank and Gaza. That fear explains why they would not budge on allowing Palestinians an army as part of previous two-state negotiations. That fear explains why they would give back the Sinai but not the geographical high ground of the Golan Heights. That fear explains why the Israeli Left completely collapsed after the Second Intifada. They're happy to give part of the West Bank back in two state negotiations, but they would never, ever, allow Palestine an army. Because of security fears. The Palestine-Israeli conflict is this positive feedback loop caused by a desire for security conflicting with a desire for freedom. We're in the terminal doom spiral phase of this feedback loop right now.
I wouldn't use the term propaganda account for several reasons, one of which is that on any divisive topic, no one agrees about what counts as 'propaganda'. People mostly use that word to refer to points they strongly disagree with. In that way, it's a lot like the word censorship. For moderation purposes, it's better to use different words so we don't get tangled in definitional arguments.
But it's against HN's rules to use the site primarily for political battle (among other things), and when an account does that repeatedly and ignores our requests to stop, we usually end up banning it. I did that a while ago in this case.
