Iran presents an interesting and somewhat contradictory issue. They did indeed supply the resistance with Farj 5s and helped build tunnels etc. However Iran's role as a regional power is under threat. Most obviously in Syria where their ally Assad is in big trouble. It is significant that Hamas have distanced themselves from Assad in recent years. Earlier this year they publicly supported the Syrian opposition and condemned Assad. Iran for its part is building relations with smaller resistance groups such as Islamic Jihad.
What we are seeing is the growth of the Muslim Brotherhood across the region. It is in power in Egypt. It is leading the protests in Jordan where it is confident enough to call for the overthrow of the King. It is amongst the Syrian opposition and it is a natural ally of Hamas who come from that tradition. I think we are witnessing Hamas move away from Iran and towards the Muslim Brotherhood and I think we are witnessing the rise of a Muslim Brotherhood axis spreading across the region something which raises interesting questions about the future relationship between Hamas and Egypt and Egypt's relationship to Israel.
I'd be interested to see how these countries within the orbit of the Muslim Brotherhood deal with Iraq, which is historically dominated by a ruling class of sunni's, but has a substantial shi'ite population more likely to side with Iran than the Muslim Brotherhood. Iraq's the faultline, looking back it's not hard to see why the US was so keen to have soldiers and a compliant government there.
