It's awful wrong to blame other countries for the current and potential US fiscal irresponsibility and the consequences. The divestment from using the dollar in International trade is borne out of the years of economic repression of other countries by the US, weaponizing the dollar, and the likes. The neo-colonialistic tendencies of the US, have shown them to be detrimental partners. Countries who are shying away from the dollar, do so to save their economy, people and sovereignty. To say it doesn't solve the problem shows that one might not even understand the problem in the first place or maybe for that person, it's a case of the only problem that matters, is the impact on the US. US policies have been wreaking havoc on developing and underdeveloped nations of the world and if they seek to fix that by shying away from the dollar, they are very much in their right and thinking of their best interest like they should have always done.
