US dollar hasn't really been backed by anything for a very long time now and this trend can not be changed and i don't think it matters any more either.
the value of dollar has been based on the power of US and the faith that the world had in that power alongside the US itself bullying everyone into using USD and nothing else.
but as US continus having internal issues including the shitton of dollar they printed this pat months and with all the stupid forign policies that pushed every ally away, the value of USD keeps decreasing.
The United States continues to be a very powerful power.
The US has nuclear weapons, a huge army, a strong economy, technology, an educated population, and good demographics. However, in recent years, many mistakes have been made in domestic and foreign policy. These mistakes led to the strengthening of China's position and deterioration of relations with Russia and Germany. At the same time, the economic situation in the United States has deteriorated significantly (this is due to the huge external debt).
At the same time, until recently, the US dollar was the world's reserve currency.
This imposes a great deal of responsibility on the United States - such a country simply does not have the right to make mistakes and behave inappropriately.
