I blame the whole entire thing on Biden for letting Afghanistan fall so quickly to the Taliban, encouraging Russia to invade Ukraine. However, now that the damage is done, we have to support Ukraine. Putin has turned into a Hitler and if he isn't stopped in his tracks, Putin will pick off one country at a time in the area until the Soviet Union is back in existence and then even more than that.
I'll bet you would blame Biden if your picnic was rained out. It was Trump who signed a surrender document and withdrew forces at a rapid rate while the Taliban violated the agreement they signed. Biden did not encourage Putin to do anything. Putin did that.
