Putin is under pressure to act, Miller added, and time is not on his side.
“Russia is already engaged in what could only be described as a ‘drip-drip’ invasion already, but the Ukrainian military continues to recapture territory from the separatists,” Miller said.

“If Putin does not invade soon,” he added, “the separatist movement, which was largely manufactured by the Kremlin anyway, may ultimately have been crushed.”
