Biden is 大智若愚. He was determined to destroy all remnant forces of the Soviet Union, plotted for decades and strongly influenced US foreign policy towards creating a rift between EU and Russia. Russia can destroy Ukraine but can’t take on the entire Europe + US.
Biden looks blur. As commander in chief you would expect someone that's more alert when deciding to make decisions regarding the war in Ukraine. Hopefully he's not being manipulated by his handlers in the white house. Although I have to say that probably with Trump around these wouldn't be a war with Russia and Ukraine. Biden really looks like he's losing the plot which is worrying especially when you catch him off guard
