A criminal is punished by law and bears the consequences same as an invader will be sanctioned by the international community! Russian dictator Putin breaks the rule and he and his government will bear the consequences!
The EU, US and their allies have agreed to cut off major Russian banks from the main international payment system, Swift one hour ago.
It means Russia will not be able to use swift to do business with most foreign countries! The worse situation is that the Russian economy will be crashed soon.
Putin is responsible for the war and his government bears the pain.
