The joke of sanctions implemented by the EU and the US, and they are a joke, since EU continues to import gas from Russia, and SWIFT use continues by the Russian Federation, is a symptom of the same attitude seen on many Ukraine residents just 48 hours ago.
A kind of cognitive disconnect between the obvious war coming your way, and a refusal to accept it, until it is at your door.
You have a ex-president of the United States openly praising the Russian president on the media, and also US TV networks openly doing the treasonous job of promoting Russian views in the US. If the Russian army quickly overtakes Ukraine you have Russian troops staring across the border to Polish troops. Some of the small countries that are now members of NATO, still have small pockets of Russian speaking communities. You think Russia will not claim they are also being discriminated and need another peace keeping operation?
In case of a conflict between Russia and a NATO member, it's mushroom clouds we are looking into. So I find your legalistic concerns incredibly detached from the seriousness of the current situation.
