More sanctions on Russia will just make Russia more independent and have a good base to convince other countries to bypass the dollar and stop trading with the US ...Sanctions will never work on Russia ...a very small exemple is when EU applied sanctions on Russia , the country arrived to improve it's own internal market and local products so they are very close in self sufficiency and also right after sanctions 2 years ago ...Russia surpassed the US and become the world first Weath exporter in the world and banned and incriminate GMOs !
