Petro dollar collapses too. The west blames China and probably Russia for economic disaster and huge unemployment (even though it's the wests fault for not planning for that inevitable reality).

Civil unrest in the west, potentially war with China unless NATO collapses first.

Many bad things for the people in the west since our entire political economic system depends on cheap energy facilitating "infinite" growth (of GDP at least).

Though, hopefully leaders in the west are smarter than trying to beat a dead horse.

The US will be very unhappy.
