-Do you think Russia can survive, and how can they survive the harsh economic realities that they are about to experience? Are the sanctions sufficient to push Putin into a decision to stop the invasion?
for the short term they can still survive, maybe 2-3 years the Russian economy can still survive the sanctions imposed. But if their alliance like China also drops sanctions, Russia won't be fine. so it all depends on their alliance country. Besides, I'm sure they'd predicted all of that from the start. so before they invade, they probably already have a solution for this.
China wont drop sanctions. In fact, I think China is the one who is winning in this war. Russia have sanctions. Europe will have increased prices on fuel, gas, which means prices will be increased on everything. And here comes China with cheap goods and cheap production. All the manufactures that have production on Russian territory will move to China. As well as they will (or will try) to supply Russia with sanctioned goods and services. The world can try to manipulate and drop sanctions China. But these guy have everything and can make everything and live in their own world. The world can not survive without China and will keep calm.
