(Answer to Sputnik about my thoughts about Biden endorsing a renewal of START II.)
(Pretty hypothetical questions. I don’t think Biden will be chosen and I am confident Trump will be re-elected.)
Biden is running as Obama’s heir, therefore it’s not surprising that he would support START 2; he will probably claim he had a lot to do with it.
The Cold War left four important arms treaties. The ABM Treaty (1972) forbade anti ballistic missiles, the INF Treaty (1987) forbade intermediate range nuclear weapons, the CFE Treaty (1990 and modified) limited conventional weapons and the START Treaty (1991 and renewed) limited nuclear weapons. Washington (Bush II) abrogated the ABM Treaty in 2002; NATO never ratified the modified CFE Treaty and invented so many new conditions that Russia, which had ratified it, pulled out in 2015 (Obama); Washington has just pulled out of the INF Treaty (Trump). All that remains is the New START Treaty of 2011 (Obama) which Trump has said he doesn’t like and. So if he’s POTUS in 2021, that’s probably gone too.
So it looks as if the entire arms control regime inherited from the Cold War will be gone in a few years: in all cases the initiative has come from Washington although Moscow has (of course) been blamed.
It’s a good question whether anyone in the Democratic base is even aware of this reality or much interested. Maybe Biden can awaken people to the danger. Or is the Democratic Party too far down the rabbit hole of Trump conspiracies, PC obsessions and social justice warriors to notice important things?
