Zelenskiy has been leading his country through Russia’s brutal assault for 19 months, all the time fighting on another front to wring the weapons and finance he needs from his US and European supporters. Now he suspects that President Joe Biden’s commitment is wavering and other leaders may be taking their cue from the US, according to a person who met with him recently.

He grew very emotional at times during that discussion, the person said, and was scathing in his criticism of nations that he said weren’t delivering weapons quickly enough.
