I spoke at length with London's Monocle Radio on Friday night about the European Union's forthcoming cut-off of oil imports from Iran, the timing and manner of its implementation, and the consequences for Tehran.
There are lots of take-away points from the interview but the headlines may be: 1) the EU decision is going to be announced at the end of January, but probably will not take effect until months later, as alternative supplies are assured; 2) yes, this will be a major blow to Iran, both in symbolism and in economic impact.
The discussion begins at the 6:08 mark.
