Glad to see hyperbole is alive and well.
Putin did in fact indicate to Poroshenko at the Minsk peace Conference that he expected the approximately 8,000 Ukrainian defenders in Debeltseve to surrender to the Russian separatists as part of the ceasefire agreement. Poroshenko and the Ukrainians denied being fully surrounded and isolated, so Putin has ordered his /Russian forces to reduce Debaltseve to rubble until the Ukrainian defenders agree to surrender the city and the defensive pocket being nearly surrounded by the pro-Russian and Russian armed forces.
