Russia Derangement Syndrome

Let me see if I can get this straight:

1. The West imposes unprecedented sanctions of Russia, freezing its dollar assets in the West, locking it out of SWIFT, prohibiting and effectively cancelling business deals....

2. Russia says, "OK, but then if you want to buy our gas, you'll have to pay for it in rubles.

3. Germany shrieks "BLACKMAIL!!!!"

So Germany gets to pay for gas in dollars which Russia can't access because of the sanctions?

The West can deal with the present crisis in whatever way it wants, but it shouldn't loose its marbles in the process.
