“The consequences are that the civil war in Syria, extremists, extremist groups will continue to use the vacuum (the government – ed.), existing in Syria to expand their operations which include – apparently – attacks on Russian interests, perhaps even on the Russian cities. And Russia continues to send military home in body bags for the bodies, and they (the Russians — ed.) will continue to lose resources, perhaps even the planes again,” said Kirby, asked about the possible consequences of continued violence in Syria.
