Because of Russian money.
Exactly, and now that Russian money is basically worthless, things should /hopefully/ be dramatically different - Although everyone is understandably on tiptoes about it.
It seems like the first point of action has to be from the Russian people themselves. They need to rise up and revolt against the government, which many already are. So a step in the right direction. The Kremlin cannot handle both domestic and international issues at the same time, they can't even invade Ukraine properly if what's happened the last week+ is anything to go by. I would not be surprised if all the cool modern military tech as either just for show or they basically sold stuff to further bolster Russian billionaire pockets etc.
