A thread full of people who have no clue what is even going on in the world. Russia's economy cant survive in the long run with sanctions.... Its plain and simple, if you think otherwise you are clueless to how the international economy fundamentally works and should probably stick to speculations.
Do you even know character of these sanctions or are you simply talking out of your ass? I bet the latter, actually Kremlin already benefitted from crisis as they bought back cheaply strategic companies privatized (stolen) in the Yeltsin era. Pigs panic sold shares of Sberbank, Lukoil and few others as much as 30% below their market value during takeover of Crymea. Price has since recovered.
So far the EU/USA sanctions limited themselves to specific credit providers and small group of influental Russians. Non-issue for large export based economy. Even then price of corn is already up by 25% (Russia is responsible for 17% of export of this vital resource) Everybody is fearful of escalating as the world market is already fragile and ripe for correction.
