FAA can write regulations that are favorable to the U.S. interests as long as it is seen to have integrity so the major course correction needed to save it's credibility as a long term advantage to the national aviation industry? Not credibility in terms of actually avoiding craters full of bodies better than anyone else on the planet to date(737MAX is still 737?), but only as a petty strategic trade war tool? This implies moving from fake news to fake aviation security, it seems.

No. The FAA has regulations. Other countries trust that they are properly applied as part of the certification process by the FAA, and so they don’t make Boeing do much certification work for each country they’re going to sell to. If the FAA is seen as being lax in enforcement of its own regs in a material way, other countries can’t just outsource the certification oversight work to the FAA because they can’t be trusted.
