In recent developments, U.S., European, and Arab mediators have been working tirelessly to prevent the cross-border attacks between Israel and Lebanon's Hezbollah militants from triggering a wider Middle East war, a scenario that the world has been fearing for months. With hopes fading for a cease-fire in Israel's conflict with Hamas in Gaza, which could potentially calm the attacks by Hezbollah and other Iranian-allied militias, American and European officials have issued warnings to Hezbollah, cautioning against underestimating Israel's military might.

The warnings emphasize that Hezbollah should not rely on the United States or any other country to hold off Israeli leaders if they decide to execute battle-ready plans for an offensive into Lebanon. Additionally, the officials have also advised Hezbollah not to overestimate their fighters' capabilities in handling the consequences of such a major conflict.

While there has been a slight leveling off of the escalating strikes between Israel and Hezbollah along the Lebanese border, the exchange continues to pose concerns. The recent shift in hostilities has ignited hope for a temporary ease in immediate fears as the United States deployed an amphibious assault ship, accompanied by a Marine expeditionary force, to deter the possibility of a wider conflict. However, it remains unclear whether Israel or Hezbollah has mutually decided to decrease their attacks in order to avoid provoking an Israeli invasion into Lebanon.

Gerald Feierstein, a former senior U.S. diplomat in the Middle East, acknowledges that despite the temporary lull, Israeli preparations indicate an expectation of a conflict of a different magnitude. He stresses the message being conveyed to Hezbollah: that they should not overestimate their abilities. The conflict was triggered when Hamas launched attacks on Israel in Gaza, and Hezbollah responded by launching rockets into northern Israel, vowing to continue until a cease-fire is reached. The violence has resulted in the displacement of tens of thousands of civilians along the border.

The possibility of a full-scale war between Israel and Hezbollah is a major concern for Lebanon, with Defense Secretary Lloyd Austin stating that it would be a catastrophe and could easily escalate into a regional war with severe consequences for the entire Middle East. Israel has pledged to unleash massive devastation on Lebanon if a full-blown war erupts, while analysts expect other Iran-allied militias in the region to respond more forcefully than they have for Hamas, thereby potentially attracting ideologically motivated militants.

Efforts to mediate the conflict are underway, with U.S. senior adviser Amos Hochstein leading discussions on Israel-Hezbollah tensions. The French, Qataris, Egyptians, and other European nations are also actively involved in the mediation process. The White House has expressed its support for Israel's right to defend itself while cautioning against opening a second front. However, there is a realization that a second front in the Middle East conflict cannot be ruled out.

The Biden administration has been pushing for a cease-fire agreement between Israel and Hamas in Gaza, which would significantly contribute to easing tensions on the Lebanon-Israel border. Although negotiations have stalled, the U.S. has presented new language aimed at jumpstarting the discussions. An extended truce, coupled with the release of Israeli hostages and Palestinian prisoners, has been proposed by President Biden as a three-phase deal.

As the efforts continue, hopes remain that the potential wind-down of major combat in Gaza, specifically in the city of Rafah, may lead Hezbollah to scale back its rocket attacks on Israel. However, experts caution that without a cease-fire in Gaza, any temporary calm along the Lebanon-Israel border is insufficient to ensure lasting peace.

The situation remains fluid, with mediators working tirelessly to find a peaceful resolution and prevent the gravest scenario of a wider conflict in the Middle East from unfolding.
