The role of the dollar is not simply a function of the size of the U.S banking system. It has many historical and structural reasons. But be that as it may, my point is that the U.S has that special role and shouldn't abuse it for political purposes.
And about genocide: I think we both know that the set of countries against which the U.S has imposed sanctions is not equivalent to the set of countries that have committed genocide. It's a list of political enemies of the U.S.
Not all countries on the list have comitted genocide and there are quite a few U.S allies and trading partners that have committed genocide or other brutal human rights violations. They are not on the list because it's politically convenient or very lucrative.
