Its fair to say that western sanctions have hurt the Russian economy and made life a little more difficult for ordinary Russian families, but as far as causing a political/economic collapse of Russia - there is not much evidence that the sanctions are causing grief in Russia.
And when you examine 'deals' that Russia has made since the sanctions were authorised, it may be that Russia is ahead of the game.
It can be suggested that sanctions are a very weak tool. Famously, sanctions have not worked against China (back in Mao's time), Cuba or North Korea. They weakened Iraq, but caused the 2nd world economy then operating, and helped push Iraq back into anarchy. In a way sanctions are like the disfellowshipping sanctions used by our former loving brothers, some buckle under the pressure, but others get their backs up and decide they will never give in.
But back to the "deals."
It can be argued that sanctions pushed Russia closer to China. Some 100 trillions of dollars in deals between Russia and China have been announced since the sanctions were applied. New pipelines (oil and gas) are already under construction, and a new VFT (Very Fast Train- i.e. 300km/hour) rail-line route, is being surveyed eastward from Moscow. Details of armament deals have not been disclosed, but it is rumoured that the deals included the very latest Sukhoi fighter plane, the equivalent of the F-35 and the latest anti-aircraft rocket system.
I've counted some five different arrangements (inclusive of the China deals) that the Russians have made since the Americans applied sanctions.
I'll post these separately. The first will be the Russian-Saudi Arabia agreements just announced.
