Americans and the Russians are leaping over the threshold in Aleppo – almost.
Note the rhetoric: US State Department Spokesman, John Kirby, says:
Extremist groups will continue to exploit the vacuums in Syria to expand their operations, which could include attacks against Russian interests, perhaps even Russian cities. Russia will continue to send troops home in body bags, and will continue to lose resources, perhaps even aircraft...(if the war continues)more Russian lives will be lost, more Russian aircraft will be shot down.
