It's utterly sickening that people keep repeating that Gazans have been advised to move south.
They were advised to move in the middle of Oct before the war started in earnest.
Only a sick human, devoid of all empathy would continue to claim that the civilian population are too stupid or stubborn to move.
No-one has said this ^ no-one. at. all. So please stop your emotive, inflammatory, rhetoric.
As for the claim Hamas are preventing them leaving; if you had a nice secure bunker with a tunnel network with plenty of supplies I doubt you'd be above ground directing traffic whilst bombs were raining down FFS.
This explains why Hamas won't let them leave
It isn't the IDF's fault that Hamas are a bunch of murdering psychopaths.
However, it is made very clear in the Hamas Charter, which identified Hamas as the Muslim Brotherhood in Palestine and declares its members to be Muslims who "fear God and raise the banner of Jihad in the face of the oppressors". The charter states that "our struggle against the Jews is very great and very serious" and calls for the eventual creation of an Islamic State in Palestine, in place of Israel and the Palestinian Territories and the obliteration or dissolution of Israel.
