Why doesn’t China and Russia care more about Iran getting nuclear weapons? I would say the prevailing wisdom is business/economic considerations combined with “It’s not our problem.”

If Iran and Israel engage in a nuclear war, wouldn’t both countries, along with the rest of the world suffer great economic harm? Who could predict what such an exchange would do to Iran’s oil flow? What would happen to the world markets? What would the US public say about continuing to trade with China and Russia? Aside from economics, how would the US be changed? Would the US public and politicians not be enraged and never again say the cost of war war is not worth preemptive attacks? Would the US not have a pretty good reason for attacking N. Korea with nukes? And what would that do to the world economy?

Has Russia and China considered these possibilities and decided they are outweighed by current business/economic benefits? Have they calculated that Israel will solve the problem itself before Iran gets nukes? Or has China and Russia calculated that Iran will not use nukes once acquired and the resultant emboldened Iran is not going to harm them?
