A - You and especially british media take "Gaza Health Ministry" (aka: Hamas) numbers at their face value?
B - It is not Israel that ended the ceasefire. The agreement was agreed to run in three stages, each going 42 days, starting on January, 19th, 2025. Hamas broke the agreements by numerous agreements, namely in staging pr scenarios out of simple hostage handovers, but not stopping there. And they keep holding back hostages, in order to make time to milk goods and more fighters from israel prisons, and stock up for their next terror attacks.
Regarding where the arabs from Gaza can go: Where they came from, gypt, Syria, and where the Arabs of the region got their own land: Jordan. But really, there are muslim countries all over the world. The self-named palestinians just would have to learn to exist without terror leadership, jihad, and international help.
