It'll partly depend on what internal housecleaning—or perhaps fumigation—and reform happens in the US.

While it is unlikely to occur, imagine the international effect if the US resoundingly impeached and removed of a lawless president, and Congress formalized a lot of international agreements into statute rather than delegating too much to the executive branch.

Nah, this problem is systemic, and much older than the current administration. Or has everyone forgotten the "anthrax" in a test tube? The invisible WMDs? The fake news about soldiers tossing babies out of incubators? Setting up a web of lies and attacking is a foundational value of the United States.
