Literally every country controls what passes their borders...

"The" refers to Israel's border by normal English rules. Seems you're being deliberately obtuse.

And it's absurd to think Egypt didn't have control over their own border. Egypt didn't want Palestinians crossing for other reasons (they have a history of terrorism in moderate Muslim states).

Why do you hold this opinion? Israel literally controls the Rafah border crossing between Egypt and Gaza, and has bombed it several times. If Egypt and Gaza agreed to let anything pass, there's a good chance Israel would bomb it again.

Also, "[nationality/ethnic group of people] have a history of terrorism" is racist.

>Because they don't want Israel's prisoners to spill over into their country.

Israel's zionists has a pretty long history of terrorism as well, even against the British.
