According to the US State Department, Russia is either complicit or incompetent? So which is it? It seems highly unlikely that Russia couldn't have known what Syria was doing giving Russian troops are housed at the base which launched the chemical attacks on Syrian civilians. And it's not like Assad hasn't done this before. Russia promised the US to keep chemical weapons out of the hands of Assad. It does appear Russia has been complicit in the gassing of Syrians. How could Russia share an airbase with Assad and not know what was going on? Given how these things usually develop, I suspect it is both. I suspect Russia is both complicit and incompetent. The US is now launching an investigation into Russian complicity. So which is it? Is Russia complicit, incompetent,or both? If so, what should the US and allied nations do?
