US President Joe Biden and Ukrainian President Volodymyr Zelensky spoke by phone for just under an hour on Sunday, with Biden promising that the US would respond “swiftly and decisively” to any potential Russian military action. However, Biden didn’t stray from his promise not to put US troops in Ukraine.
According to a White House readout of the call, “President Biden reaffirmed the commitment of the United States to Ukraine’s sovereignty and territorial integrity,” and “made clear that the United States would respond swiftly and decisively, together with its Allies and partners, to any further Russian aggression against Ukraine.”
The call signals no change in the US’ posture, which is that in the event of military action by Russia, economic sanctions, and not military intervention, will be Washington’s weapon of choice.
