RE:RE:RE:Why is the Biden administration not refilling the SPRIt is a well known fact that sanctions on a country don't work. There is a long list of countries over the years/centuries that have sucessfully withstood sanctions and Russia is no exception.
The best way to test whether sanctions are working or not is to "follow the money". The best and simplest way to do this is to look at the relative exchange rate of the country being sanctioned compared to the US dollar.
So what is the evidence?
Year over year the Russian rouble has appreciated 47% compared to the US dollar. No other currency comes close to that level of appreciation.
