As Israel ponders its response to Iran, as allies urge restraint, as battles targeting Tehran proxies rage in Lebanon, let's begin with a simple fact of geography: Iran and Israel don’t share a common border. Since October 8, Tehran has been touting a so-called axis of resistance; what Israelis brand a ring of fire, with Iranian-backed militants in Lebanon, Gaza, Yemen and Syria ... to which the US would add Iraq.

With the past two weeks of military successes, are we seeing a short run that restores a measure of aura for Israeli might, or something more profound that could deal a blow to these non-state actors and upend the region's balance in ways unseen since the 1979 Iranian revolution? 

One can look at Middle East rivalries and alliances through the prism of Israel's relations with its neighbours, but also through the up-and-down Sunni-Shia divide.

In the middle are the likes of Jordan, whose military shot down Iranian missiles on Tuesday night. Its own population sees no good outcome in the current spike in tensions. With the US and Europe ineffective in stopping this spiral the past 12 months, is there any bold initiative that can turn the current nightmare into a positive dynamic?
