“Remember when I gave Iran ten days to MAKE A DEAL or OPEN UP THE HORMUZ STRAIT. Time is running out – 48 hours before all Hell will reign down on them. Glory be to GOD!” US President Donald Trump warned on Truth Social on Saturday.
By doing so, he renewed his ultimatum as the war remains unresolved and as American forces continue searching for a missing US pilot.
Trump’s message is meant to generate urgency and anchor control of the situation. Unfortunately, his warning has also been undermined by none other than Trump himself.
Before considering whether Trump’s new threat will alter Iran’s calculations, it is necessary to remember what happened the last time he reached for the same device.
On March 22, Trump gave Tehran 48 hours to reopen the Strait of Hormuz or face American strikes on Iranian energy and infrastructure.
Shortly afterward, he backed away from the cliff edge, saying there had been “very good and productive” talks. By and by, Iranian officials and media denied that any meaningful negotiations had occurred.
If Trump was able to “Truth Social” his way out of his last deadline, then why won’t he do it again? When a deadline is announced and then softened, extended, or reinterpreted, one’s enemies feel comfortable testing it. They begin to distinguish between statements intended to change events and those trying to maintain appearances.
A single ultimatum can generate pressure. A repeated ultimatum that expires without visible consequences can backfire. It can signal hesitation, encourage delay, and tell Tehran that time may still be its most reliable ally.
Iran not treating warnings as ultimatums
There are already signs that Iran is not treating these warnings as the White House might intend. Recent reporting indicates that ceasefire efforts have reached a standstill.
The Islamic Republic rejected a US proposal for a 48-hour truce, and Iranian officials have continued to deny Trump’s public claims that serious diplomatic movement is underway. That is not the behavior of a regime that believes the clock is genuinely about to run out.
Iran’s rulers are ideological, ruthless, and often reckless, but they are not naive. They study patterns. They hear the threats, measure the pauses, and ask whether Washington is trying to end the war decisively or simply cycle through another 48 hours of public pressure followed by another tactical retreat.
If the answer appears to be the latter, then every fresh ultimatum that comes and goes without decisive follow-through does not restore deterrence. It erodes it.
None of this means that every public threat must culminate in military action. Serious governments must preserve room for adaptation. Intelligence can change, and diplomatic channels can open unexpectedly.
The Jerusalem Post trusts the decision-makers in the US and Israel to make the right calls in a conflict that is exposing civilians, soldiers, shipping lanes, and energy markets to enormous risk.
But trust does not cancel responsibility. Leaders who issue public ultimatums assume an obligation either to enforce them or to explain, credibly and quickly, why a different course better serves the strategic objective.
Israel, meanwhile, has priorities of its own that require sharper definition, especially in Lebanon. In recent days, the message on Hezbollah has been firm but not entirely coherent. The IDF has warned that if Lebanon does not disarm Hezbollah, Israel will. Defense Minister Israel Katz has likewise emphasized that disarming Hezbollah remains a priority.
Yet the military has also acknowledged that fully disarming Hezbollah would require a full-scale invasion of Lebanon, something it does not plan to undertake. That gap between declared objectives and available means is not a minor communications flaw.
Rather, it is a strategic problem, and one that Hezbollah has definitely picked up on as the North remains under heavy missile and drone barrages.
For two and a half years, Israelis have endured a condition that no democracy should be expected to normalize: continuous war, rolling mobilization, repeated funerals, disrupted schooling, recurring displacement, and the persistent fear that one front can flare up just as another seems to quiet.
Israel is prepared to endure hardship until the region is safer than it was before October 7. But a public that continues to show resilience deserves more than malleable deadlines.
What it deserves is seriousness, coherence, and leaders who understand that strategic patience is not the same as strategic delay, and that a nation at war should not be dragged from one deadline to the next.
