A wider war in the Middle East, from Hamas to Hezbollah and now Iran

The long-feared “wider war” in the Middle East is here.

For the past 360 days, since the images of the slaughter of about 1,200 people in Israel last Oct. 7 flashed around the world, President Joe Biden has warned at every turn against allowing a terrorist attack by Hamas to spread into a conflict with Iran’s other proxy force, Hezbollah, and ultimately with Iran itself.

Now, after Israel assassinated the Hezbollah chief, Hassan Nasrallah, and began a ground invasion of Lebanon, and after Iran retaliated Tuesday by launching nearly 200 missiles at Israel, it has turned into one of the region’s most dangerous moments since the Arab-Israeli War of 1967.

The main questions now are how much the conflict might intensify and whether the United States’ own forces will get more directly involved.

The past few days may prove to have been a turning point. Since Israel killed Nasrallah on Friday, the Biden administration has been shifting from cautioning against a wider war to trying to manage it. Officials have defended Israel’s right to strike back at Iran, but Biden said Wednesday that he would not support direct attacks on its nuclear facilities that could tip the conflict out of control, warning that Israel must respond “proportionally.”

This is the spiral that Biden has cautioned against repeatedly, but has not been able to stop, even with 40,000 U.S. forces in the region.

“From Israel’s perspective, we have been in a regional war since Oct. 7, and that war is now an all-out war,” said Michael Oren, a former Israeli ambassador to the United States, a historian and one of the country’s more hawkish diplomats. “We are in a war for our national survival, period.” Winning over the next few weeks, he said, is a “duty” for a nation “created in the aftermath of the Holocaust.”

The unknown is how Prime Minister Benjamin Netanyahu of Israel will interpret that existential mission as he weighs how, not whether, to strike back at Iran.

Biden’s warnings started early, on his visit to Israel less than two weeks after Oct. 7, to show solidarity after one of the most gruesome terrorist attacks of modern times.

That was before Israel obliterated the Gaza Strip from above and sent its military in on the ground, against Biden’s advice in a series of heated conversations with Netanyahu. It was before Israel booby-trapped pagers and walkie-talkies used by Hezbollah that exploded across Lebanon, and before Netanyahu approved the plan to kill Nasrallah and systematically decapitate much of the Hezbollah leadership.

It was before the administration hinted last week that Israel had agreed to join a 21-day cease-fire, only to be defied, again, by Netanyahu, who then turned around and authorized strikes into Lebanon.

To Biden’s critics on the right, this is all the result of American hesitance, his unwillingness to back Israel unconditionally and his understandable tendency to nuance every promise of aid with a warning not to make the mistakes the United States made after the Sept. 11 attacks.

To his critics on the left, what has happened in the past 10 days is another example of Biden’s failure to make use of American leverage over Israel, including the threat of withholding American weapons after more than 41,000 people have died in Gaza. While several thousand of those killed were almost certainly Hamas leaders or fighters, a vast majority were civilians.

To many Israelis, this escalation was inevitable, another chapter in a struggle for survival that began with the nation’s creation in 1948.

Netanyahu clearly has the United States’ blessing to retaliate against Iran. At the White House on Tuesday, Jake Sullivan, Biden’s national security adviser, said the Iranian attack had been “defeated and ineffective,” largely because of the coordinated efforts of U.S. and Israeli forces, who had spent months planning how to intercept the incoming missiles. “We have made clear that there will be consequences — severe consequences — for this attack, and we will work with Israel to make that the case,” Sullivan told reporters.

Sullivan said the White House was consulting extensively with Israel, including with the prime minister’s office, to formulate the appropriate response. He emphasized the degree of communication, leaving unsaid the obvious: Biden and Netanyahu barely talked as Israel took the fight to Lebanon, planned the Nasrallah operation and the ground invasion.

But once Iran, a lethal threat to Israel with military powers that Hamas and Hezbollah can only aspire to, directly entered the fray, America’s tone and strategy changed — and so have Israel’s.

The behind-the-scenes negotiations now boil down to Netanyahu’s intent. Will he send another message to Iran about what Israel could do in the future, as he did in April when he aimed at military facilities in the holy city of Isfahan? Will he take out oil production facilities and ports?

Or will he aim directly for the facilities he has threatened to strike for years, starting with the underground Natanz facility where Iran is enriching uranium to near-bomb grade?

U.S. officials believe they can persuade Netanyahu to make his point without setting off a full-blown war. But they concede that the Israeli prime minister may see the next five weeks until the American presidential election as a ripe moment to try to set that program back by years. After all, former President Donald Trump would not complain about a major attack on Iran’s military infrastructure, and Democrats cannot afford to be accused of restraining Israel after Tuesday’s missile attack.

“Israel will do its best to be disproportionate,” Gen. Wesley K. Clark, a former supreme allied commander of NATO, said on CNN on Tuesday. White House officials take the opposite view: Netanyahu, they say, cannot afford to be anything but proportionate.

This new era runs many risks. There is the risk that Iran, frustrated by the failure of its missile force to break through Israeli and American weapons, will convince itself that it is finally time to race for a nuclear weapon, viewing that risky move as the only way to hold off an adversary that has penetrated iPhones and pagers and computer systems. There is the risk that despite the election of a moderate-sounding new Iranian president, Iran’s Revolutionary Guard will win the country’s internal arguments and double down on its missile programs and agents of influence.

“A full-scale war, or even a more limited one, could be devastating for Lebanon, Israel and the region,” said Jonathan Panikoff, the director of the Scowcroft Middle East Security Initiative at the Atlantic Council. “But from it, unexpected opportunities will also come — to undermine Iranian malign influence in the region, for example, by actively impeding its efforts to reconstitute Hezbollah. And a new administration should be prepared to take advantage of them.”

That is what old wars and hot wars do. They create new power dynamics, vacuums to be filled.

But there remains the danger that wider wars, once begun, take years to put back in the box. And the presence of nuclear weapons, ballistic missiles and an instinct to escalate creates a particularly toxic brew.
