The White House reiterated on Thursday that we are in a window where we believe a Russian assault on Ukraine could happen at any time. A false pretext for invasion could take many forms, the White House warned, and the US is bracing for more false reporting from Russian state media in the coming days. The White House said that, in his remarks at the UN, Secretary of State Anthony Blinken will signal an intense commitment to diplomacy. The White House reiterated that it has serious concerns about the movement of Russian troops at Ukraine's borders, and the US has been very clear and transparent about how action the US and its allies will take to deter a Russian invasion.
