In the first three month of the assault on Gaza, the ratio of Al Qassam fighters killed to noncombatants killed was over 1:10. It has since improved marked and is closer to 1:2. I think the protesters can take some credit for that, as well as the ICC (not ICJ, the author seems to have missed the distinction).
Likewise, the Jordanian, French, and US aid airdrops that continue to this day and the recent IDF decision to allow humanitarian aid to access Gaza during daytime can be seen as an accomplishment of the protests and legal actions (including ICJ charges against both the Israel and Hamas leaderships).
I. a boomer, was arrest six times during the Vietnam War. It went on MUCH longer than it ought to have, but I firmly believe our opposition helped bring it to an end ultimately.
I note one false note in this peace: "Hamas Rebels". The Al Qassam Brigade is an out-and-out terrorist operation. Before October, the rockets they launched into Israel were too inaccurate to have a military impact; they were meant solely to terrorize civilians.
On the other had, Al Qassam represents only a small portion of Hamas, the great majority of whom are civil servant trying to manage a big city under very difficult cricumstance. Hamas' leadership should be routed, but the bureaucrats will be needed to successfully rebuild Gaza. Israel would be well-advised to make a distinction between Hamas fighters and Hamas functionaries. I would not be in the least surprised if the great majority of the functionaries are seething with anger at the stupidity of the Al Qassam leaders.
