Why Iran is escalating against Israel to protect its ‘Resistance Axis’

Jerusalem, for its part, has made clear that Tehran’s insistence on linking any deal to a ceasefire in Lebanon will not constrain its response to Hezbollah attacks

Iran’s decision to strike at Israel in response to Israel’s bombing raid on a Hezbollah command centre in the Dahiyeh area of Beirut reflects the extent to which Teheran is determined to maintain its network of proxies across the region. The latest exchange between Israel and Iran was probably inevitable, given Iran’s determination to maintain this strong and mutually obligatory connection. Israel, for its part, has made clear that it is not prepared to acquiesce to a situation where Hezbollah launches attacks on Israeli population centres, while Jerusalem’s response remains restricted to southern Lebanon. Iran is, by escalating, attempting to impose de facto rules of engagement which are unacceptable to Israel.

From Teheran’s point of view, the renewed clashes with Israel have the side benefit of accentuating the differences in the US and Israeli positions regarding the conflict at the present time. While the US appears to be seeking to reach an agreement with Iran as soon as possible, Israel is making clear that Iran’s insistence on including a ceasefire in Lebanon in any such deal will not dictate the range or nature of Israel’s response to Hezbollah attacks.

Iran’s effort to protect its Lebanese client shows the centrality of Iran’s proxy network to Teheran’s regional ambitions and to its projection of power in the Middle East. The Islamic Revolutionary Guard Corps’ (IRGC) methods in proxy warfare represent the most innovative and the most successful element of the Iranian regime’s regional strategy. The Lebanese Hezbollah organisation is the jewel in the crown of this particular structure. The proxy network is not a sideshow for Teheran. It is the main event. Hence Teheran’s efforts to protect it and to act with its components in unison.

In this regard, it is noteworthy that despite the heavy blows suffered by Iran and its allies in the course of the last three years, Teheran’s regional network remains bruised, depleted, but intact. To be sure, Iran’s longstanding ally in Damascus, the Assad regime, is gone. But that regime was in many ways an exception in the pro-Iran camp, in its nature as an old-style Arab nationalist military dictatorship, and in its secular orientation. Its fall means that the Iran-led regional alliance now consists exclusively of Islamist organisations which combine political and military roles under a single leadership structure. They are the means by which Iran seeks to dominate the region. It has made considerable advances using these methods towards this goal.
