NATO and other US colonies submitted harder to US under Biden. In part, it made political sense to boost US in order to prevent Trump again. The CIA loyal colonial institutions that made that happen though, are pushing for total capitulation instead of the escape hatch that China/world provides.
Fentanyl, FYI is used in hospitals extensively because it is a cheaper opiate on a per dose basis. It is not a cause of opiate addiction, but instead has a high risk of overdose death as a result of typically accidental use instead of heroin. Anti-immigration positions in Canada are gaining strength mostly because of the systemic collapse of the last 4 years of subjugation creates pessimism over sustainability that is required for policies like education or immigration to eventually pay off.
Instead of banning fentanyl, and growing opium in Canadian greenhouses for traditional opiate industry, and limiting immigration even more, including visa requirements from countries Trump hates, Canada is begging for the privilege of funding perpetual Ukraine war, and acting as force multiplier on war with China.
OTOH, this latest call is a ploy to get US-Canada to jointly isolate from the world. Mexico has already been cooperative with China, and has a massive opportunity to become Central and South American manufacturing hub in addition to significant cost of living comparative advantage.
Even if US accepts Canada as part of its island, it will continue escalation of demands.
