President Donald Trump announced Monday that Israel and Hezbollah had agreed to halt attacks following a flurry of calls with Israeli Prime Minister Benjamin Netanyahu and intermediaries linked to the Iranian-backed group.
Hours earlier, however, Iran suspended talks with Washington, citing Israel's military operations in Lebanon and threatening to open new fronts in the conflict.
The diplomatic turmoil comes as Israel carries out its deepest military operations in Lebanon in more than two decades.
Tehran argues the operations violate the broader ceasefire framework established after the US-Iran war, while critics counter that Iran helped create the crisis by insisting Lebanon be included in ceasefire discussions and then backing Hezbollah attacks that prompted Israel's response.
Turning Lebanon into leverage
For some analysts, Iran's actions suggest a regime that believes it emerged from the war with more leverage than many expected.
"I fear that the Iranians are doing what they're doing because they feel that they have the upper hand," Yaakov Katz, an Israeli-American journalist and author of While Israel Slept, told Iran International.
Katz said Tehran may see itself as having weathered the conflict relatively well. The regime survived, its military remains intact despite significant losses, its nuclear program remains unresolved and Washington is still negotiating with it.
From that perspective, Iran may believe it can broaden the scope of diplomacy beyond its nuclear program and force the United States to account for developments in Lebanon.
That is precisely what concerns Katz.
"It's a disaster to connect the two," he said.
If Washington accepts Lebanon as part of the negotiating framework, Katz argues, Tehran could repeatedly use Hezbollah's confrontation with Israel as leverage whenever future diplomatic disputes arise.
The concern comes as Trump balances two competing objectives: preventing a wider regional war while preserving a diplomatic path with Tehran.
On Monday, Iranian-linked media warned that Tehran could expand pressure to the Bab el-Mandeb Strait, another vital global shipping route, while tensions remain elevated in the Strait of Hormuz. The threats renewed concerns about global energy supplies and the economic fallout from a broader regional confrontation.
The price of Tehran's red lines
Eric Mandel, founder of the Middle East Political and Information Network, believes the Lebanon crisis, threats to maritime shipping and suspension of talks are all part of a broader Iranian strategy.
"This is a coordinated strategy that they are using," he told Iran International. "The biggest part of it is that they are looking to delay."
Mandel argues Tehran is attempting to stretch out negotiations while increasing economic and geopolitical pressure on Washington.
The goal, he says, is to test whether the Trump administration is willing to sustain a prolonged confrontation or whether concerns over oil prices, shipping disruptions and economic instability will eventually force concessions.
He believes Iran benefits from uncertainty.
"I think what Iran wants overall is to create a global recession," Mandel said.
Danny Citrinowicz of Israel's Institute for National Security Studies and former head of the Iran branch in Israeli military intelligence sees the situation somewhat differently.
While Katz and Mandel largely view Tehran's behavior through the lens of leverage and strategy, Citrinowicz argues that ideology remains a central factor.
He says Iran does not view Hezbollah, its missile arsenal and its enrichment program as bargaining chips that can simply be traded away. Rather, they are core pillars of the Islamic Republic.
"They cannot sit aside and not retaliate. That is their mentality," Citrinowicz told Iran International.
From Tehran's perspective, he argues, failing to respond to Israeli operations in Lebanon would amount to abandoning a strategic commitment to Hezbollah and undermining principles the regime considers fundamental to its survival.
That distinction may prove critical as Washington weighs its next move.
For Katz, Iran is attempting to exploit Trump's desire for a deal by transforming Lebanon into a bargaining chip. For Mandel, Tehran is deliberately prolonging the crisis to increase pressure on the United States. For Citrinowicz, Iran's actions are driven less by tactical calculations than by ideological red lines it believes it cannot abandon.
What all three agree on is that Lebanon is no longer a side issue. It has become a central test of the fragile diplomacy between Washington and Tehran.
If Trump pressures Israel to halt operations, Tehran may claim it forced Washington's hand. If he does not, Iran appears prepared to use Lebanon, Hormuz and potentially other fronts to argue that the ceasefire framework has already collapsed.
Either way, Tehran appears willing to increase the costs associated with both diplomacy and confrontation as it seeks to shape the next phase of negotiations.
