When Hamas came to power, they murdered all the PA officials, especially the policemen. Dragged them into the streets, shot them through the head. Hamas is no different than ISIS - they enforce Islamic hudud law.
Now, I'd never say this out loud - I'd get dogpiled - but is there an argument to be made, however odd it may sound... that IDF is liberating Gaza from Islamic terrorism, as the USA did in Mosul, for example?
