Trump will send in troops to "restore order", "prevent bloodshed" and "protect strategic resources". Once he has done that, there is still the thorny issue that Ottawa will not allow them to separate, so Trump will recognize Alberta as an independent country.
In addition to the reasons provided above, there is also the threat that the Canadian government is too close to the Chinese and can not be trusted with information, and by this time, they will have bought a lot of the Canadian oil industry. This is possible because Canada just signed a major trade deal with China yesterday that allows them access to the oil industry, and they are to collaborate closely.
With Alberta as a protectorate, a pipeline can easily be built to go south to the US, and there will likely be a pipeline to cross the Yukon into Alaska as part of a new trade route with Russia. You guys discussed Trump and Putin probably talking about a cross Bering strait tunnel to access Siberian resources, and with Alberta and the Canadian North also protectorates, a highway and pipelines could be easily built.
Incidentally, it should be noted that the leader of the Conservative opposition, Pierre Polievre, is now based in Alberta. He lost his seat in Ontario, and an MP from Alberta gave up his seat and Polievre won the seat in a by-election. It seems odd that he moved to Alberta to obtain a seat, but it is possible this is just chance, but there is the possibility that he may have been pre-positioned in Alberta to take on a leadership role, either pro-keep Canada together or more likely Alberta independence, not sure. Whatever role he takes on, he would have the support of many across the country, my guess is that it would be for the independence side, and he would stay in Parliament and work a deal with Trump for further Canadian provincial integration and trade with the US , keeping what's left of Canada as a much poorer version of the present.
Saskatchewan would probably also separate quickly. Quebec would probably separate. Newfoundland, with its oil resources, and strategic location, would probably also separate. Canada will just be a hodge podge of poor provinces, and extreme unemployment and no money to fund the social welfare net. A country with a lot of chaos, will probably require intervention if too much trouble is tricking into the US.
NATO ARTICLE 5
But then there is NATO's pesky article 5, that might cause some major problems in this scenario. The European countries would be required to intervene, that could be a problem.
Enter the latest talk on Greenland. If Trump wants to intervene in Canada, in the next 18-36 months, he has to get NATO out of the way. We believe his current actions are being done to cause the destruction of NATO, in advance of anything that happens in Canada. If Trump sends even a single expeditionary force to Greenland and claims an area, it triggers article 5. Will the rest of NATO dare to do anything? Maybe Denmark will respond, but the rest probably will not, and the US would then pull out of NATO, leading the disintegration of NATO. The remains would probably regroup as a European focused organization against the threat of Russia, and the new threat of the US dominating the North Atlantic, with its other obvious partner the UK.
So with NATO out of the way, the move of troops into Alberta and Saskatchewan to protect strategic resources will not be difficult for the US, and many Canadians will be primed to support this action, as Carney is doing everything that he can to destroy living standards.
