LOL - Russia was continually fighting in Ukraine during the trump years. There was no need to make a major attack because Putin was slowly getting what he wanted. Hero worship is a terrible thing.
"Experts say Trump’s actions weakened Ukraine, divided NATO, emboldened Putin and helped get us to where we are today. And even with Trump no longer in office, his impact lives on in the form of Putin-friendly commentary in
conservative media and from some
Republican lawmakers.
“One of the key reasons Putin probably felt comfortable launching the invasion of Ukraine was the extent to which the West has been weakened and destabilized, and democracy undermined, and political divisions sown, in the five years since he attacked our election in 2016,” said Garrett Graff, a historian and journalist with expertise in national security and Cold War issues."
