Almost many countries do not have sovereignty because they all depend on the US dollar. So there doesn't have to be a war before the sovereignty of each country is destroyed, without war America can take sovereignty in every country. It can be seen that currently each country has its own currency, but why do international transactions have to use dollars? Does this include sovereignty in a country? I do not think so. The solution is that each country should have its own sovereignty, each country should use Bitcoin as an international transaction. However, many will reject this, so it is not surprising that many countries want to drop bitcoin because they are afraid of bitcoin that they cannot control.
World transactions still use the dollar currency because currently many countries prefer the dollar as a currency that can be accepted in international trade, but currently China is trying hard to compete with the dollar and wants to change their international currency to the Chinese currency. But actually, if you say international transactions, then currently there is cryptocurrency, which is one solution.
