Thank you for calling attention to this. But I don't see a reason for mod intervention here yet, because the community handles this issue very well on its own.
It takes 5 people to close a question. In both examples, all people reviewed as "leave open". So unless we actually get a coordinated group of at least 5 people who conspire to close all questions about topics they don't like and coordinate their timing well enough to get them closed before the review queue gets to them, there is no reason to worry. And in that case we can act on a question-by-question basis. When you see a question which got closed for a reason you don't consider valid, post on meta so the community can discuss what to do with the question.
And if that gets annoying, then we can consider to swing the mod-hammer against people who abuse the close questions privilege.
Besides, I could conceive why one would want to close both of these two questions for a reason which has nothing to do with antizionism: They are both very speculative. I see little point in closing them now, because they are both over a year old and got good answers. But if they were new questions I could fully understand why someone would vote to close.
