The time to invest is basically when there's blood on the streets and I guess now is better a time than ever to do that - big investors like Soros, Rogers, Mobius are jumping in. Bottom line its the biggest country in the world, oil is *always* going to be in demand and Russia also has shit loads of untapped resources. I think the risk of going bust is not definitely not that high.
If the global economy is crap, demand for oil is lower but if it "stays crap" for long enough someone will make war and war always drives the price up. So the main long term issue is geopolitical....
Perhaps you missed it: We’re at war with Russia - MarketWatch
"The U.S. has been waging economic, financial, trade, and political war against Russia and even kinetic war-by-proxy in Ukraine. Worryingly, nobody in power in the U.S. or Europe really seems willing to tell us exactly why."
