Something interesting to ponder is that dedollarisation can be a bigger threat to Europe than to United States. As the dedollarisation grows, all these printed dollars in global circulation would have to go back to their origin (USA) but that would cause hyperultra inflation. There's is this law that would be enforced to prevent those dollars from coming back to keep the inflation "exported". In a world where Europe is left dollarised, EU will have to bear that inflation.

This is exactly why a lot of politicians in Europe have been warning about staying "close" to US as the sinking ship. Macron is only one of them.

Well, yes and no.
- No because economy alone is not what makes a country "super power". There are a lot of different factors involving geopolitical presence and effect, geography, infrastructures, resources, military, "reach", international allies, population, etc. and even when it comes to economy you can't just analyze it based on one factor like inflation or GDP growth. Even each of these factors alone can not be analyzed based on raw numbers and one-liner twitter like comments.
- Yes because if we only focus on economy, the past year is an excellent indication of the massive potential of growth Iran's economy has and the extremely ready infrastructure like ready to use factories and production lines that used to work at a tiny portion of their capacity, top quality products in many fields including high tech that can easily eliminate their foreign counterparts and most importantly ultra cheap production cost which helps that elimination in the competitive global scene. This past year Iran has been heavily dedollarising by the way.
