I expect a lot of sanctions to backfire. Like Russia migrating from swift to the newish Chinese system and never coming back, Russia nationalizing foreign companies operating on their territory (as they already hinted with McDonald's)

Lot of these "second wave sanctions" sound like virtue signaling, these company probably would have had a greater impact by using Russian profits to fuel the Ukranian effort and/or help the refugees

I know we already shot ourself in the foot, a necessary evil, time will tell if we also shot the other one.

Guess it will depend if Russia can use it's internal resources to create an independent economy, or whether they become another North Korea.

Maybe they get lucky and collapse like the USSR and some of the oblasts and republics get a fresh start as their own new nations.

I wonder how to square with the fact that continuing to do business in Russia would mean continuing to pay taxes, that would fund a war-waging government.

Maybe they can point Russians to an online store outside Russia's jurisdiction. Sadly for the ordinary Russian, Visa and MasterCard have also disabled the ability to use their cards overseas (within Russia it seems they outsourced the processing to a Russian company, which is still functioning).
