Again, the sanctions haven't done everything they were supposed to do because the Russians have done workarounds. I'm not an economics specialist, but I will say from my understanding of history that the only time sanctions have actually worked and you get the political effect was in South Africa, where the apartheid sanctions took place. Apartheid ended because of sanctions.
The Americans have had sanctions on Cuba since 1959 and they keep going. For Iran, North Korea, you name it, sanctions do not usually effect the political outcomes the people putting on the sanctions want.
The Russians have done workarounds. They are able to have their internal economy.... They have actually strengthened their internal economy. The Russian ammunition factories are working around the clock. There's a Russian tank factory in Siberia taking old T-62s and remodelling them constantly. They're running around the clock, and they're putting them into the front line.
