First of all, you need to define "Yahu" so we know who we are really hearing from. It can have many meanings, some not very nice. Second, it is false that 50,000 civilians were killed. Hamas does not distinguish between dead terrorists and innocent civilians killed as human shields or because they were not allowed to leave combat zones. It does not include natural deaths. So the total figure, which Hamas says is now about 47,000, includes the almost 18,000 terrorists that have been killed, and at least 10,000 deaths from disease, old age, unrelated accidents. At most 25,000 civilians have died, everyone a tragedy, everyone due to Hamas.
The reality: over 99% of the people who lived in Gaza before the pogrom are still alive. That's not genocide, that's not mass slaughter. That's a very carefully run war, where all care is taken to avoid death. Look at what Assad did next door in Syria, carpet bombing cities wiping our people ten thousand at a time. Yes, 25,000 dead Gazans is a tragedy. Hamas started the war, and they refuse to end it by doing the right thing: surrender, lay down arms, release all hostages.
If Israel did not care about children, why did they oversee polio vaccinations for 99% of all Gazan children? Assad fell because Israel humbled Iran and Ukraine tied down Russia. Lebanon is much freer from Hezbollah thanks to Israel. The people of Gaza will someday recognize that Hamas was the enemy.
