Hammas local command is built in tunnels under an hospital in Gaza Strip. The options Israel have are: A. Don't hurt Hammad to save Palestinians but suffer more attacks on Israelis. B. Kill every last hammas member, getting some Palestinians dead, but saving its own citizans.
Shity options, one has to be made.
On the grand scale of things, Hammad directly killed more Palestinians than Israel did. They murdered membera of FATAH for example.
So if this war actually eliminate Hammas (spoiler: it won't) than it will save the life of many Palestinians that don't agree with Hammas.
But wannabe leftists on the Interwebs from safe westarn countries want to be cute and defend Hammas cus they are supposdly the opersed party.
