1. Trump had NordStream2 stopped with sanctions. Biden lifted them.
What has the administration actually done on Russia? Below is a chronological list of its actions and official statements since January 20, 2017. During that period, the administration has taken 27 actions on Russia.

2. Where has Biden acted as the world's policeman? I remember when ISIS spread like wildfire under Obama, and then Trump killed it.
True Biden has given Ukraine military aid, but both parties support that as it weakens Russia's military.
3,. Your claim that "the EU would have been conquered" is nonsense. Russia does NOT want to tangle with NATO.
4. Trump's destruction of ISIS shows that your claim of isolationism is bullshit.
5. One more thing. Biden's moronic withdrawal from AFG got him "held in CONTEMPT" by Britain. Giving bad actors $85b of US military equipment is also stupid.
