From the Russian standpoint, the US government’s idiocy and duplicity towards Russia will continue regardless of who is president. From The Saker at unz.com:
It sure looks like Biden will take over the White House one way or another, and while Trump and his supporters might still try a few things, the political correlation of forces inside the US ruling classes is clearly against Trump. As for the “deplorables” – they have been neutralized by stealing the election. Which means that Russia will soon face the most rabidly russophobic gang of messianic Neocons in history. So what can the world expect next?
The Dems are not meaningfully different from the Republicans. True, the Dems blame Russia for everything, while the Republicans blame China. Not much of a difference here: it is all about hate and scapegoating. And both of these factions of the oligarchic Uniparty like to blame Iran for, well, being located in the “wrong” part of the world, the Middle-East, which all US politicians (and not to mention their Israeli masters) want to control. As for the Israel Lobby, it has been trying to trigger a US attack on Iran for many decades. Recent US moves of key personnel and bombers might indicate that discussions of an attack on Iran are still very much taking place.
I don’t believe that these fundamental directions in US foreign policy will change much.
