The Pentagon is developing options for a potential major escalation against Iran that could involve ground troops and an intensified bombing campaign, according to a report published on March 26, 2026 [1]. US officials and other sources described the potential escalation as a “final blow” that would give President Trump more leverage and room to “declare victory” [1].
President Trump has not yet made a decision on the matter, according to the report [1]. The report indicates that a major escalation was likely if negotiations made no progress, and there is no sign that real diplomacy is underway despite Trump’s public claims of talks [1].
Specific military options reportedly under consideration include invading or blockading Kharg Island, Iran’s main oil export hub [1]. Another option is the invasion of Larak Island, a strategic outpost that helps Iran solidify its control of the Strait of Hormuz [1].
The seizure of the strategic island of Abu Musa and two smaller islands, which lie near the western entrance to the strait and are controlled by Iran but also claimed by the UAE, is also being considered [1]. Blocking or seizing ships exporting Iranian oil on the eastern side of the Hormuz Strait is another potential operation [1].
A further operation being considered is sending troops deep inside Iran to secure Tehran’s stockpile of uranium enriched at 60%, though it is believed to be buried under rubble following airstrikes in June 2025, making access unclear [1].
The report states that escalation is likely if negotiations make no progress [1]. Iranian officials have rejected a 15-point proposal that the US passed through mediators and have set their own conditions to end the war [1]. On March 25, White House Press Secretary Karoline Leavitt threatened that President Trump was ready to “unleash hell” on Iran [1].
President Trump publicly claimed that Iran wants “to make a deal,” and asserted U.S. envoys have been holding talks with a “respected” Iranian leader, according to an Associated Press report [2]. However, Iran has denied these claims, stating no talks have happened [2]. This reflects the ongoing disconnect between public statements and diplomatic realities.
About 5,000 US Marines and several thousand US Army Airborne soldiers appear to be on their way to the Middle East as the Pentagon prepares for ground attacks, according to the report [1]. These operations are described as fraught with risk and will likely result in major US casualties since any ground force would face significant and sustained Iranian missile and drone attacks [1].
Separate reporting indicates that President Trump is considering sending an additional 10,000 ground troops, according to The Wall Street Journal [1]. The Iranian Tasnim News Agency cited a military source stating that Iran is able to tap more than one million fighters for a potential ground confrontation [3]. This underscores the scale of the potential conflict.
In the meantime, US-Israeli strikes continue to pound Iran, and the Iranian military continues to launch attacks on Israel and US bases across the region [1]. According to a report from The New York Times, the majority of US bases in the Middle East are now basically uninhabitable due to Iranian strikes [1].
The report concludes that any such major ground operation would likely prolong the war [1]. The source for the initial Axios report is Barak Ravid, a former IDF intelligence officer [1]. The developments are contributing to global economic instability, with energy prices rising and financial markets reacting to the uncertainty, as noted in other contemporaneous reports [4].
The planning for a potential major escalation, including the use of ground forces, represents a significant shift in the U.S. approach to the conflict with Iran. While diplomatic avenues are publicly discussed, military preparations continue apace. The operational risks, as described by sources, are high, and the regional and global consequences of such an escalation remain uncertain.
