This with no shadow of doubt will only create problems for them Europeans, which of course its happening already. Russia still stands firmly despite all the sanctions imposed on her. It is indeed a huge necessity to the Western sides.
Russia is able to sustain for now but eventually, if EU countries will find a way to look for alternatives this will be the start for Russia to worry and of course they will move more aggressively because of this. I wonder what's the situation right now between Russia and Ukraine, but I hope they can settle this one as soon as possible because many are already affected by this. In my country we are still paying a huge gas cost as well, I guess we are all affected.
