One of them had to miss an entire quarter because Israel just wouldn't allow him to leave. He has never been back to Palestine since then because another detainment or missed visa problem, etc. would derail his career.
Terrible.
Even in the current ceasefire terms, there's an explicit provision to have Israel agree to let the injured leave for treatment to neighbouring countries and be allowed to come back to the Strip.
Despite arguments to contrary, I can see why some claim it is an open-air prison.
That aspect of Gaza was in place long before Israel had anything to do with the strip.
Based on that, he must have obtained a special permit to leave Palestine and fly to the US for higher education, but this had to be approved by Israel or he could not leave Palestine or transit through Ben Gurion Airport (remember the Palestinian's international airport was bombed into rubble a decade ago or so). One year they denied him for some Kafkaesque reason, I presume. By the time he sorted it out he had to arrange with the school to take a leave and start again the next quarter
Egypt has an airport just west of Gaza. They have a visa exclusive program for Palestinians. And that's not new.
So based on the story, if you presume Israel was Kafkaesque then you must also presume that Egypt was at least as Kafkaesque if he was unable to leave from there.
Or worse... he was unwilling.
And yet, the story is about Israel for some reason. I'd ask why, but I presume to know the answer. Again, this is a shrug towards bias.
This is all speculative in terms of how it relates to your friend. All this to make the point that bias and generalizing about things, and a desire to blame people one has been taught to hate, can be detrimental to one's success.
I agree, you should see the way people are doing this under my very comment about my friend.
In the end, I am sure he knew more than most people about the options truly available to him. He was never biased or hating of anyone. Those who know him today would know
