If we all (very justifiably) believe that Trump would truly become a dictator if he wins in November, then it is clear that the president has the ability to wield tremendous power to radically remake our system.
Which means that Bidens failure to act on any given issue is a choice.

We should ask ourselves why he is prioritizing procedural norms over real improvements to Americans standards of living. Why do we accept that The Rules are more important than our lives?
The United States is the global hegemon. We are not bound by any agreement. And, inevitably, our lawyers can find ways for us to act however we want in such a way that it does not technically violate any agreement we are a party to. No one can bind us against our will.
And no, Israel does not have "veto power" before any international body. Certainly not at the UN or WTO
