War Crimes

Whenever I see posts criticizing Israel or the US of blowing up hospitals, etc, they happen to coincide with people who think the wars they/we are waging are wrong to begin with. Which makes me confused. Would they support the wars if we didn't blow up hospitals and only killed terrorists, etc? Do these people oppose war in general? Or this particular war? More often than not, I think these folks actually favor war and are just wish-casting that we or Israel lose. To be honest.
