The question is what will hurt, what will cause pain in people who are actually making these decisions that are breaking international law and international conventions? That's a....
The economic sanctions that are being discussed using the Iran model apparently can hardly work regarding Russia, just because of the structure of its exports—unless Europe decides to live without Russian gas, which would have an enormous economic cost for Europe.
But inasmuch as we, meaning the international community, have talked about the issue of personal sanctions.... That was on the agenda for three months in Maidan, and was finally used at the end. Why are we not using it against Russia, at least? Because the same contradictions, which others would call hypocrisy, apply. That is, the discourse is all aggressively anti-western. It's all about western conspiracies. But their money, their children, their houses, and their vacations are all in the west, not in Russia. That was the reality in Ukraine. Actually, we have reports that in Switzerland and Austria, post-Maidan or not, they're freezing and really going after the assets.
So doing that is certainly a first step.
