I don't think that website implies what you're thinking. The only significant thing that happened in 1971 is that Nixon suspended the convertibility of the dollar into gold, giving the US leeway to run unlimited deficits, paying for imports with paper.
Now, America wants to reduce its debt and curb industrial powers like the EU, Japan, China, etc. but it doesn't want to give up its exorbitant privilege that got it into the debt whole in the first place.
