Emphasis mine.If they really wanted to help the people of Gaza, they'd first let the foreign people through, those trapped at the border waiting to be repatriated, and then they'd either provide sufficient humanitarian aid or allow immigration from Gaza. But even other Muslim countries won't allow the Palestinians in. They don't seem to want them there, which is the most logical solution.
There are ... reasons.
Most likely it's been tried and the results were not good ?
