You’re making vague statements that the children of Gaza should be evacuated, but that’s not a solution unless you can tell me where they would be evacuated to.
There are two and a half million people in the Gaza Strip. What place is going to accept two and a half million Palestinian refugees? Bear in mind that millions of Palestinians have already ended up as refugees throughout the region and that is already considered a huge problem. Nobody wants even more to deal with. So what country? Even if there were magical teleporters to get them there and everyone was willing to leave their homes forever, who’s going to take them in and support them?
