Most of your responses amount to deflection to subjects you'd rather talk about.
No, these were simply examples that show that the West has been wrong on most international issues.
Of course, the Soviet Union has made any mistakes too, e.g. the examples you gave. And I meant since after the Korean War, basically after Stalin was gone.
The Cuban missile crisis was not merely a miscalculation by the Soviet Union. Sure, they did miscalculate about the way the US would react, but then part ofthe deal that resolved the crisis was that the US would remove its missiles from Turkey.
Then your analysis that Russian policy w.r.t. Iran would likely create problems is based on assumptions that I don't think are supported by facts. It assumes that Iran has a nuclear weapons program which I don't think the US believes is true at this moment.
I don't think the US would be patient and let Iran come with proposals to discuss its nuclear program to address Western concerns, if the US were concerned about the existence of an active nuclear program. The concerns have much more to do with the idea that Iran could, in the future, decide to leave the NPT and make nuclear weapons, if they develop the technology to enrich uranium on an industrial scale.
That fear is based on what we think the Iranian intentions are and we want Iran to come clean about what they've done in the past. But Iran is already under sanctions and they will not do anything more than sticking to the usual IAEA inspections. Extra inspections that the IAEA wants to carry out are not approved by Iran.
It seems to me that this whole standoff is caused by the US pressing for sanctions against Iran that were clearly premature. This issue was never going to be resolved in any other way than the World agreeing with Iran that Iran has the right to enrich uranium on an industrial scale, while Iran agrees that there are legitimate concerns stemming from their past behavior that Iran has to address, e.g. by allowing extra inspections.
I think if you go back a few years just before the UNSC voted for sanctions and read what Lavrov and Dr. Rice were saying, you see that Dr. Rice was the one who was wrong. Her proposals failed to deliver (Iran is still enriching uranium right now and it has not answered questions about its past program and it is not allowing the extra inspections the IAEA wants to carry out).
If Russia had acted on their objections and vetoed the UN resolution demanding Iran to stop enriching uranium, then it may well be the case that another UN resolution would have been passed in which Iran would have been required to cooporate with the extra IAEA inspections, extra monitoring of their enrichment ectivities, come clean on their past behaviour etc.
Then the issue would have been solved. The concession the West would have been made would be that they would have agreed to not close the doomsday loophole that Iran would decide to leave the NPT and use the enrichment technology they have developed to make a bomb. But as of now, we would be better off, as we would have far more monitoring of the Iranian nuclear program.
The sitiuation today is that while we have not agreed with Iran enriching uranium and have passed a UN resolution saying that Iran has to stop enriching uranium, Iran is still enriching uranium. So, by aiming for more, we have gained less. Less information on Iran's nuclear program and the feared (but unrealistic) doomsday scenario is still there.
