A much more important question is whether United States has the military capability to start a war to prevent dedollarization?
From what we've seen over the past 2 decades, and how US military policy has been proxy wars; I'd say NO.
But this doesn't mean we aren't going to see more conflicts like the ongoing Russian-NATO war, this means we will see more proxy wars where US stands back while others fight and destroy their own countries (eg. China-Taiwan).
I do not know what are your beliefs and feelings against the USA, but i am not a USA citizen and from what i have heard and read from the news in my cycle, and from what i have learned so far and from my experience, the USA will really find a way to squash them all as you have said France is already facing consequences and Russia has also faced some when they tried to take INR instead of US dollars and then they have no other means to use those INR, and now they have useless Indian currency. (
source). After using INR now they have shifted to Yuan and i think they will face the same again. The point is, the US economy is very strong despite the fact that they are facing several banking crises and debt ceiling problems but eventually, they will overcome them and will come up with such the bold moves that they made when Saddam Hussain declare to use the Pond as a payment method instead of US dollar in Iraq for the trade of their Oil and US invaded Iraq after that with the slogan (mission name " freedom of Iraq" something like that)
I hope you get the answer to your question about the military capability of the US to start a war against dedollarization. But the interesting thing or climax is, at that time it was only one country and now its a group of atomic countries which have bound to one aim, and in my point the US will not make the mistake of using military equipment against dedollarization scheme instead they will play politics and other things to deal it.
Remember that for the supporters of "de-dollarization" - if you have facts, you give arguments, you can soberly assess the situation, express your thoughts and think - you are definitely a "pro-American puppet" and "adorer of the USA"
I have been laughing at these dedollarizers for many years and probably decades. People live in anger and envy towards the USA (or rather towards the free world, the world of opportunities), constantly inventing fairy tales for themselves about the "collapse of the USA". But at the same time, very often they themselves live in countries where there are no prospects, where everything is at the level, if not of the Stone Age, then of the past spiral of progress, where power is usurped and there are no freedoms. This, of course, infuriates them, and they have to self-satisfy with self-hypnosis about the collapse of the United States. Although they could take and make their country better than the United States. But this is a difficult path, you have to work, think, fight... And a simple neurosimulation is simple and does not require effort
PS Bringing them some facts is useless
