As American diplomats scurry to flee Ukraine, President Joe Biden said Russia is poised to spread misery throughout the country if it follows up its massive troop buildup with an invasion. Biden spoke by phone with Russian President Vladimir Putin for an hour on Saturday. Earlier Saturday, the State Department announced that most U.S. diplomatic personnel are being pulled out of Ukraine, which is currently encircled by about 130,000 Russian troops. The call focused on “Russia’s escalating military buildup on the borders of Ukraine,” according to a White House readout. “President Biden was clear that, if Russia undertakes a further invasion of Ukraine, the United States together with our Allies and partners will respond decisively and impose swift and severe costs on Russia. “President Biden reiterated that a further Russian invasion of Ukraine would produce widespread human suffering and diminish Russia’s standing.
