A good critique of the arguments presented by the pro-Biden/Zelensky virtue signalers has been made by Lushington D, Brady on the BFD website:
“Either sovereignty matters, or it doesn’t. As Caitlin Johnstone rightly says, International law is a meaningless concept when it only applies to people the US power alliance doesn’t like. This is not, as is so often claimed, a ‘whataboutism’: it’s a direct challenge to the arguments made against Putin.
“If George W. Bush, Tony Blair or Barack Obama can violate another country’s sovereignty, then Putin can claim justification for doing it, too.”
