The instinct in Washington is to dismiss the latest flare-up in violence along Israel’s northern border as just another incident in a long-running cycle of violence involving Hezbollah and the Israel Defense Forces. The State Department will condemn the attack on Israel but it will call for restraint and calm. Their expectation, echoed in much of the media, is that once the smoke clears, the combatants will return to an armed and hostile truce enabling diplomats to concentrate on more important things like the administration’s pursuit of détente with Iran. But whether or not the shooting continues in the coming days, this incident, in which two Israeli soldiers were killed by terrorists firing over an international border, must be understood as intrinsically connected to the broader issue of U.S. relations with Iran and its nuclear program. The fighting is a wake-up call to the West alerting it to the fact that Tehran’s real purpose is not, as President Obama hopes, “to get right with the world,” but to dominate the region and threaten Israel and moderate Arab nations.

The border violence is generally being reported as part of a tit-for-tat exchange between Hezbollah and Israel. Today’s incident, in which anti-tank shells were fired at Israeli vehicles travelling on a civilian road from three miles away inside Lebanon, is seen by many as retaliation for Israel’s strike at a Hezbollah missile base inside Syria last week in which, among others, an Iranian general was killed. Iran has warned Israel that it would retaliate and it is thought that today is proof that they meant what they said.

But there is more to this than the need for Hezbollah to do the bidding of its Iranian paymasters or even for it to gain revenge for the death of the terrorists slain with Tehran’s ballistic missile expert, one of whom was the son of a slain commander of the group. The point of setting up that base in Syria, near the Golan Heights, was to create a launching pad to hit the Jewish state without bringing down the wrath of the Israel Defense Forces on Lebanon, as was the case during the 2006 war that was set off by similar cross-border raids. But the reason why Hezbollah and Iran were so interested in strengthening their ability to rain down destruction on Israeli civilian targets is that Tehran sees itself as being locked in a permanent war with Israel as well as with Arab states in the region.

This is more than obvious to anyone who pays the slightest attention to Iranian policy as well as its use of terrorists to advance its policy goals. Hezbollah is an arm of Iranian foreign policy as proved by its use as shock troops in the effort to preserve the rule of Tehran’s ally Bashar Assad in Syria.

This exposes the fallacy that lies at the heart of the current U.S. approach to Iran. President Obama is convinced that sooner or later he will be able to persuade the Islamist regime to accept a weak nuclear deal that will enable him to withdraw sanctions on the regime and start working toward an amicable relationship. The idea of such an entente is ludicrous since the ideology of the Iranian regime is implacably hostile to the United States. Moreover, their goal is not integration into the region but rather domination of it, something that will be facilitated once it becomes clear it is a threshold nuclear state (even if no bomb is actually constructed) as well as by its use of its Hezbollah auxiliaries and a renewed alliance with Hamas.

Seen from that perspective, the administration’s zeal for a deal with Iran is not merely misguided because Iran has no intention of abiding by any agreement and that it will use the nuclear infrastructure that the West seems poised to allow it to keep to continue a pursuit of a weapon. Rather, what makes it truly disastrous is that an embrace of Iran will encourage its adventurism in Iraq, Syria, Lebanon, as well as along Israel’s northern and southern borders. An Iran that is permitted to become a nuclear threshold state will not only be vastly more powerful than it is today but in a position to directly threaten Israeli security and that of Jordan and perhaps even Egypt and Saudi Arabia. The fighting along Israel’s northern border is just a tease of what may come once Hezbollah is protected by an Iran that believes the U.S. has granted it impunity to pursue its aggressive agenda.

Instead of dismissing the border fighting, the White House should be realizing that it is headed down a perilous path in its pursuit of friendship with Iran. If it doesn’t turn back soon, today’s violence may be just a foreshadowing of the atrocities that will follow.
