Where’s Egypt in all of this? They also have a border and they also keep it shut.
Israel doesn't allow goods to be imported into Gaza from Egypt, all goods have to go through Israel. That is why there are tunnels. Only people are allowed by Israel to cross the border to/from Egypt but Israel also decides who gets to enter Gaza.
They do consult IDF and Israeli government, but the narrative, that Israel is 100% controlling all borders to Gaza is not factual and untrue.
