Iran has 'military advantage over US and allies in Middle East'

Thinktank says third parties such as Shia militias are more important to Tehran than nuclear plans

Iran now has an effective military advantage over the US and its allies in the Middle East because of its ability to wage war using third parties such as Shia militias and insurgents, according to a military thinktank.

In one of the most detailed assessments of Iran's strategy and doctrine across Lebanon, Syria, Iraq and Yemen, the International Institute for Strategic Studies (IISS) concludes Iran's "third party capability" has become Tehran's weapon of choice.
