I have to agree with Moscow in this case.
I guess Putin just told the UN to F#CK OFF.
More countries need to do this, Israel for starters.
When you are not fighting a defined military, with uniforms, you don’t know who is or isn’t in the opposition except by their actions. If they shoot at you, then go home for lunch, that house becomes a target. If they shoot at you, then go into a school, that becomes a target. Islam hides amongst the civilians. If the civilians don’t want to be targets they need to get rid of the fighters themselves. But they don’t because they support the fighters; whether they support 10% or 100% doesn’t matter. That association makes them legitimate targets. Russia knows how to win a war. We don’t.
