Russia has it's reasons for supporting the Assad regime, one being a naval installation important to Russian strategic interests in the region. That is all Russia is interested in. They have no concern for the death toll on civilians or what the west thinks. Their proxy war in Ukraine should have put any doubt about their intentions to rest. I wonder if Putin ever discovered who those troops in Crimea, wearing Russian uniforms and using Russian transport were. Since there were no Russian troops in the area, you'd think he'd be interested to know just what country was staging a war on Ukraine from Russian territory.
