You seem to be speaking as if genocide is the goal of every war. It's really not, and in fact it's against international law which most countries stick to.
Genocide is quite rare through history because generally once you have complete dominion over a people you stop and start to rebuild. In the Iraq war (which was quite an extreme war with quite a lot of rule breaking) they allowed the people to eat, they allowed aid trucks free access, there were even British hospitals that treated Iraqis. Most importantly they took measures to reduce civilian casualties, like avoiding conflict in populated areas.
This 'war' is not following any of those rules. The people are not allowed to leave, aid providers are being directly targeted, any supply of medical equipment is prevented from access.
Anyone at this point sitting on the fence going "Well both sides are in the wrong" is either misinformed or evil.
