The international value of the dollar as a reserve and trade currency is inherently tied to the behavior of the US Government and the Federal Reserve. The behavior of the US Government has been very unusual lately, and the independence of the Federal Reserve is actively being challenged. So draw from that whatever conclusions you wish.
Why is the independence of the Federal Reserve sacrosanct? For one, they should have oversight and they should have accountability. Not ever passing an audit of any kind. And the FED chairman spending $2.5B on renovations to an office complex. While misleading congress about the kinds of renovations. There should be less 'independence', if it means zero accountability.
Then the value of the USD is entirely at the whim of whoever is elected and should be priced accordingly.
