Oh no. I thought you knew the history. How did the USA try to prevent the killing of Syrians exactly? The USA made a decision to call off the attack on the Syrian positions and gave Russia a free rein.
The USA armed islamists prior to the Soviet intervention, after the government of Afghanistan asked them to intervene as per a treaty between two countries. The USA did what USA does best. Destabilise, because they did not like the standing government.
