Iran warned on Sunday, March 29, 2026, that it is “waiting” for a possible U.S. ground assault in Iran as thousands of American troops and additional military assets arrive in the Middle East.
Iranian Parliament Speaker Mohammad-Bagher Ghalibaf accused Washington of pursuing talks while secretly preparing a ground operation, and he vowed retaliation if U.S. forces enter Iranian territory.
The statement comes as the Trump administration continues to signal interest in ending the war through diplomacy, even while the Pentagon expands U.S. force posture in the U.S. Central Command region and keeps contingency options on the table.
Iran signals readiness for ground fighting
In remarks carried by Iranian state media, Ghalibaf said the United States is sending messages about negotiation and dialogue while privately planning a ground attack. He warned that Iran’s forces are prepared for U.S. troops “to enter on the ground,” and he threatened severe consequences for American forces and for U.S. regional partners.
Ghalibaf is one of the most prominent Iranian officials still publicly active after weeks of strikes killed senior leaders. His position and visibility make him a focal point for Iran’s messaging, especially as Tehran tries to project control and cohesion under wartime conditions.
Iran’s warning also fits a broader strategy aimed at deterring escalation. Tehran has repeatedly argued that any move toward ground operations would expand the war’s scope and increase the risk to U.S. forces across the region, not just at the front line.
U.S. reinforcements arrive as CENTCOM builds capacity
The U.S. military has continued reinforcing the region. U.S. Central Command said the USS Tripoli arrived in the Middle East on Saturday, March 28, 2026, as part of an influx of about 3,500 troops. CENTCOM also listed additional assets in theater, including transport and strike fighter aircraft and amphibious assault and tactical capabilities.
The scale and composition of the deployment suggest a focus on flexibility, not a single mission. Amphibious forces can support a range of tasks, including protecting U.S. installations, supporting air operations, assisting with evacuations, and providing rapid response options if conditions deteriorate.
The Pentagon has not provided detailed locations, timelines, or mission assignments for the newly arrived forces, citing operational security. That limitation has fueled speculation about possible next steps, including whether the administration is positioning forces for limited ground actions even as it publicly emphasizes diplomacy.
White House says preparations do not equal a decision
The administration has tried to separate planning from authorization. White House press secretary Karoline Leavitt said the Pentagon’s job is to prepare options and give the commander in chief maximum flexibility, and that those preparations do not mean President Donald Trump has made a decision to send troops into Iran.
Trump has also addressed the issue directly. In remarks from the Oval Office on March 20, 2026, he said he was “not putting troops anywhere,” adding that if he were planning such a move he would not publicly disclose it. His comments were intended to tamp down expectations of a ground war at a moment when the conflict has already driven major economic disruption and intensified regional instability.
A balanced reality is that war planning and war execution are different things. The Pentagon routinely develops options in fast-moving crises, including options that never occur. At the same time, deployments of command elements and large maneuver forces can shorten decision timelines if the president chooses to escalate.
