Tambo...there have already been many 10,000's of deaths, amongst them many children. And there will continue to be more into the future. We need to address the problems in Syria head on, and that means talking to the Butcher Assad, even though that sticks in the craw to do so. As long as he is throwing barrel bombs out of plane doors onto his own citizens, the situation isn't going to get better.
By the way, he was massacring his own people long before ISIS came on the scene. But the west just looked on and did nothing.
