Iran
could practice real politik and restore diplomatic relations leading
to full renormalization with Israel and be quite better off. Iran was
the second Muslim nation to recognize Israel. Israel could be an ad
hoc, positive security element for Iranians concerned about Sunni
state threats to its security, and paradoxically serve the same role
regarding Sunni concerns. Shia and Sunni governments of the Middle
East have more dangers from within and from other Muslim states than
otherwise.
Muslim
nations have problems with concentrated wealth and power that drive
strong fundamentalist morally right wing populism to work with
terrorism against conservative and even royal governments. Israel is
a popular scapegoat for historical reasons. In the present era that
dynamic is not very useful for the lawful regional governments nor
for the people or Israel. Plainly the Syrian civil war should have
been avoided along with the loss of life and suffering however the
political way of being in the region tends toward organized extremism
with support from international actors. Iran could take a low cost
and pragmatic direct action of just restoring full and normal
diplomacy with Israel and moving on toward bringing its own civil
economic and security concerns to the front of its agenda. The
practical is too often the last political item of possible choices to
be enacted.
