Nope, they're pretty decent at it. They're bad killers though. Your "logic" of ignoring Israeli war crimes and instead on Hamas rocket attacks is bad logic, bad priorities, blatant Muslim-bashing moronic goofyness.
If you want to criticize both sides, that's better. After all , Israel is doing very bad things and has been, for a very long time.. Ignoring that doesn't bode well for your credibility. Do not get me wrong, by being against the actions of Israel doesn't make me pro-Hamas.

I see...
It is NOT a "war crime" for Hamas to fire rockets at Israeli civilians and use their own as human shields...
But it IS a war crime for the IDF to strike back, doing all they can to avoid civilian deaths.
So tell me, Abdullah (slave of Allah), will you be enforcing FGM when you create the new caliphate in Palestine ??
