Not more, word is changed,
Russia and China now have powerful army
and they not more use usd, just national currency rubles and yuan for next 30 years,
for gas, oil and other.
Most people have more faith in the USD than the Ruble or Yuan.
Look at what happened to the Ruble during the 2008 collapse.. It got hammered because the USD is the actual safe haven in times of crisis. If a similar financial crisis happens again, expect the Rubble to get hammered.
