Time reports on "uneasy" relations between Kamala Harris and Zelensky

"US Vice President Kamala Harris turned down Ukraine’s suggestion of preemptive

sanctions against Moscow in February 2022, days before Russia's full-scale invasion of Ukraine. Shuster describes a meeting between Harris and Ukrainian President Volodymyr Zelensky on the sidelines of the Munich Security Conference in 2022. Both agreed that a Russian invasion would very likely happen soon.
Zelensky urged the US to impose preemptive sanctions against Russia, arguing that this would force Russian ruler Vladimir Putin to reconsider his decision to invade Ukraine, and to supply Ukraine with all the weapons it would need, including anti-aircraft systems, fighter jets and artillery.
According to the Ukrainian officials present at the meeting, Harris turned both suggestions down.
A Time source in the White House explained that the US considered the mere threat of sanctions a more effective deterrent than their imposition, and that arming Ukraine might have strengthened Putin’s belief that Ukraine was a "client state of NATO". Time suggests in the article that the 2022 meeting "set the tone for a relationship" between Zelensky and Harris "that has never been particularly warm." Pravada
