If the IDF is so moral please explain why close to 2,000 Palestinians have been murdered by the IDF whereas less than 100 Israelis have been killed in the most recent conflict?

No, it cannot. Democracy is the idea that the people determine the rules. In a true Islamic government, of which none exists currently, the limits set by God cannot be transgressed. We wouldn't be able to vote to see whether or not adultery is allowed. Though yes there are some democratic elements in the system.

War in Islam is only to be waged in cases of the enemy oppressing it's people. When we take prisoners of war, we are supposed to feed them before we feed ourselves and take care of them almost like a guest. Torture is forbidden under any circumstances. Killing is forbidden unless it's an accident or as act of justice such as executing a murderer. Saving one person is as if saving the world and killing one person outside the limits is kill killing the world. When we wage war we are not permitted to destroy religious structures. Even so much as damaging the enemies plants is forbidden unless for some reason we absolutely need to. Harming anyone who isn't fighting against you is forbidden, which includes children and non-fighting women and even soldiers that have surrendered. Rape is forbidden. Fighting the enemy after they have repented or surrendered is forbidden. Pointing a weapon at another Muslim, even in jest, if forbidden. The Quran states that fighting is prescribed even though we hate it. We are encouraged to give charity without anyone else knowing if possible.

Islam is all about peace, fighting only when necessary. Do not equate the hypocrities you see on the news with true Islam.

What most people do not know is there is no Islamic nation currently. An Islamic nation is one what follows the political structure set down by Prophet Muhammad (SAW). that was abolished in 1924. So the current actions of Muslim majority governments is not indicative of Islam.
