Last week Via Meadia reported on the possibility of enlisting key Asian states to bolster the Iranian oil embargo effort. China chickened out, while Japan announced it is committed to taking “concrete action as soon as possible to further reduce” its imports of Iranian oil. This may take some time, Japan’s spokesman conceded; as Treasury Secretary Tim Geithner said, these are “just the initial stages” of these discussions.Sanctions generally build up very slowly over time and the US campaign to tighten sanctions on Iran is going about as well as these things ever do. Yet sanctions are just one piece of the campaign to stop Iran’s nuclear program, and China and Japan’s reluctance is a good reminder to keep expectations realistic. Yesterday, another Iranian scientist was killed by an unknown assassin. Tehran was quick to accuse the US and Israel. Washington, perhaps out of concern for an Iranian-American recently sentenced to death for spying (charges which both the young man and Washington deny) disassociated itself from this latest incident, but Brig. Gen. Yoav Mordechai, an Israeli military spokesman, wrote this on his Facebook page: “I don’t know who took revenge on the Iranian scientist, but I am definitely not shedding a tear.”Publicly and secretly, the war against Iran continues.
