Israel is apparently buying Iraqi oil from the Kurdish Regional Government. What currency is being used, I do not know. I suppose so long as it is in USD, it will be fine. There has been a long standing oil embargo by Arab nations on Israel so this is pretty much a game changer in the region. Apparently money trumps religion and ideology in this instance. http://in.reuters.com/article/2014/06/20/israel-iraq-idINL6N0P11TE20140620
I would say that , that is a good thing, am glad that Israel is making up ties with Kurds, let them build a strong tie with them ,it will make such a big difference.
