I think the administration is gambling on being able to consolidate global power before anyone is going to have a chance to build anything. Europe is completely reliant on the US and US technology for defense right now, these systems took decades and trillions of dollars to build and refine, and an 800 billion EUR investment does not magically create a military industrial complex overnight. Decades ago in my early career I briefly worked on some logistics software for the Joint Strike Fighter project and had some contact with a couple of the army of contractors working on the project. The scale and complexity of this effort blows away anything else I've ever seen in my career, which includes a number of multi-billion dollar infrastructure and nuclear power projects.
Trump talks about invading Canada or Greenland and people act like it is a joke. I don't think it is.
The US is in a position to completely dictate to Europe what they will or won't do, using Russia as a proxy for now. We are 48 days in. A couple of weeks ago I replied to someone suggesting the US could provide weapons to Russia with disbelief. I no longer consider that an impossible scenario. Europe stops buying F35s? Trump tells Europe that if they don't buy them he's going to sell them to Russia. I mean that's a relatively tame response compared to the options on the table.
Right now the only chance for Europe is to stop this madness in the US. We have this "take it down" act, the executive order to produce a report advising whether or not to declare martial law, the January 6th pardon of the Proud Boys who are now effectively a paramilitary force of thousands waiting for Trump to deploy. These are all familiar elements in history and I think we are in for a bloody, bloody summer. I think we're going to see government forces opening fire on protesters, martial law declared, and the implementation of Chinese style suppression and crackdown on dissent online. Maybe attempts to strip US citizens of their citizenship and "deport" them for good measure, anything to try to sow fear into average people to not step out of line. If the administration is successful in quashing the opposition and getting everyone to go back to work, Europe could easily next on the chopping block. Remember all the things Bannon said about the EU during the first administration.
