It is by no means accidental that Russia is working actively to prevent Joe Biden from becoming president of the United States. Among the reasons is Mr. Biden’s strong, demonstrated support for Ukraine throughout his long political career. And I have no doubt whatsoever that as president he will remain a committed supporter of Ukraine, understanding that Ukraine is the lynchpin of European security. Mr. Biden will most certainly not be afraid to stand up to Vladimir Putin and hold him accountable, in contrast to Donald Trump, whose persistent obsequiousness towards the dictator boggles the mind.
