I still wondering why Euros are smaller than USD and Yuan, it's accepted by many developed countries.
Economic power will decide everything, the EU is a powerful and united bloc, but their mistake is being too dependent on the US not only economically but also militarily. It's really a pity for them. Since the outbreak of war, they started trying to reduce their energy dependence on Russia, but they ended up falling into the US trap when they were buying LNG from the US at 3 to 4 times the market price. It can be said that the EU economy is more dependent on the US than ever, and that is what the US wants, and they have succeeded. As long as the West relies on the US, the Euro will never surpass the USD.
