Feb. 12 – After another unfruitful phone call between Biden and Putin, U.S. officials warned that a Russian attack on Ukraine could come at any time. A Kremlin aide accused the West of creating “hysteria.” “The Americans are artificially inflating the hysteria around the so-called planned Russian invasion,” Kremlin aide Yuri Ushakov told reporters after the call between Biden and Putin. “The preconditions for possible provocative actions of the Ukrainian armed forces are being created alongside these allegations.”
