Taking hostages is fine, and wtf are you supposed to do if you take parents hostage? Just leave the children there in the middle of a war zone alone?
Israel is small. You can leave the children and the videos of the kids show that the children are not protected, they are hit with sticks and batons and insulted as Jews. Besides that, yes. Those kids are not Tsarist kids. Save your gray propaganda for good goals. You can also find a video in which parents are killed and a child is taken. Or children that are killed. For the outcry that a targeted and thus killed journalist by IDF forces took this ignores that there is a strategic level of Hamas which obviously encouraged what happens, as it is wide spread and communicated via established Hamas video channels and thus shown, it also got an individual vengeance and revenge component.
The actions of Hamas do show their regressive reactionary nature and that the solidarity for socialist groups in Israel is not existent within them. What we know now, too, is also that it doesn’t seem to have been a unified operation, meaning that the PFLP and other Marxist groups within Gaza are not really having impact on the strategic operations or are shut out completely.
This means that critical solidarity ought to be critical. If you do a large incursion like that you really argue that shooting young ravers and killing some after taking them hostage, is the best use of your short lived incursion? In any case I have yet to have seen text based Marxist reasoning which isn’t vibes based or goes beyond “national liberation justifies any violence”.
What is the aim here is to say any person - which includes plenty of Israeli Arabs (at least 20% of the population), also some who were at the rave - outside of Gaza and West Jordan is a legitimate aim to be killed, tortured, (sexually) assaulted, kidnapped. The terror of the guillotine and the committee for hygiene was more targeted and more in line with progressive politics than that. The “no excuse for the terror” doesn’t mean it is arbitrary terror, it is focused on revolutionary goals. They also could’ve had Marxist and pre Marxist reasoning. The operation in Palestina and Israel was not one of national liberation with a class based analysis, but one in which there are people assigned as oppressing colonialists (everyone at the rave i.e. who wasn’t coming from Gaza).
The goal of course is to weaken Israel’s tourism industry, to unify power within Gaza, to divide Israel and Saudi Arabia and have hostages to do prisoner swaps. Though it is somewhat unlikely that this nearly 60 year old practice will work as before with the current right wing government in Israel and the lack of current good will. It did strengthen unity in Israel.
If you think that then you aren’t a Marxist. Of course within Gazan society and Hamas you have reactionaries and reactionary actions. Are all? No. Plenty of groups that are or were active in Gaza aren’t reactionary. Read Marx’s https://www.marxists.org/archive/marx/works/1852/18th-brumaire/
