Well first off, I didn't ignore them, I addressed them directly. Secondly, I clearly said that they are unwinding some of these actions, just not specifically the points that you want to focus on. Lastly, Russia having them use rubles is a very sustainable measure. Why wouldn't it be sustainable?
And what is this nonsense about them dropping their exchange rate? They didn't drop their exchange rate... it took a hit initially at the start of the conflict, but it has actually gained ground and past where t was before the conflict and sanctions started.
It may be rocky for a couple of quarters, but by early 2023, their economy will be in a full sprint.
