Russia is/was ready for all of this.

- Gold backup, their own SWIFT alternatice (Mir), Digital Ruble coming soon,
- Runet have been testing since 2017, will be in full operational status on 3/11, independent of the Global Internet, they have their own social networks and apps etc.
- They have been developing agriculture heavily in the past decade or so, so food indepent.

I think it was all part of the plan since 1999 when Putin was put in power by secret service.
