Very predictable nearly immediate twitter thread reply by the assistant editor at The Grayzone News (I post so Lulu doesn't have to!) starts here:

How do they know the U.S. is planning to do all this bad stuff and that furthermore that the EU and the OAS still follow the imperialist U.S. orders, even after the credibility disaster called Trump? Well things never change you see. Nothing changes, things are always the same. For over 100 years everything stays the same (see thread!) Therefore, they don't need no fucking sources!

I am just guessing here but it's likely that's because actually there is no elected leader in the U.S., the Illuminati or Rockefeller's Trilateral Commission or the oil companies or some such are actually running the world and tell the presidents what to do, as they don't want communism to win.

(Actually, truth be told I wouldn't be surprised if there was a Biden contingency plan for a "blockade" of sorts, but that would be a blockade to avoid yet another flood of refugees, this time Nicaraguan, from making their way to the Mexican/U.S. border from Nicaragua. A "blockade" to keep Nicaraguans in Nicaragua, as it were.But that's just a guess!)
