I see three potential doomsdays scenarios:
- US invades Greenland, Canada, or another neighborhood
- Escalating trade war. US tech giants are forced to boycott its international userbase
- Massive forced USD devaluation shattering the financial markets
And of course none of the extreme, but the usual chaos.
Same as anything else. My view is you need energy and food. Get your expenses as low as possible, get enough solar and batteries, stock up on food you can keep long term in the pantry. Trump is likely driving the world towards economic turmoil, military turmoil, or both. Personally, I feel better being able to keep my own lights on.
