What's the point of flooding a region by destroying your "assets" when you could mass bombing like a deaf these villages.
After all, the west sells the war like an hegemonic move with mass slaughtering traits. Why Russia is not so heavy on using aviation, then?
US were using tomahawks on Syria for less than that.
If destruction and high toll number (aka ethnic cleansing) was the goal, they won't deliver like a grocery shop.
