Same with Hamas, really. At this point anything either organization does basically violates the "just war" (oxymoron, I know) tenant of only attacking an enemy when you believe you have a reasonable chance of success.
I'd want all militaries to disarm too, unlikely to happen unless everyone starts to agree to not get into everyone else's business.
So besides getting everyone to disarm, what could we do?
There are probably some exceptions to this rule, and yes, their occupation of the West Bank violates international law, but attacking just no longer works. Gaza lies in ruins and the IDF conducts operations in the area at will. There are currently thousands of people wrapping their electronics in aluminum foil in Lebanon. Disarming and sitting down to talk in brokered negotiations is probably more effective at this point.
