Rubio: Hardest Hits Are Yet To Come

_{By: Atlas}

Secretary of State Marco Rubio said Monday that the United States is preparing to intensify its military campaign against Iran, stating that “the hardest hits are yet to come” as administration officials briefed lawmakers on Capitol Hill.

Rubio made the remarks ahead of a closed-door session with congressional leaders, describing the next phase of operations as “even more punishing” than the strikes carried out over the previous two days. The comments followed joint U.S.–Israeli operations that targeted Iranian leadership, missile infrastructure, and naval assets.

He declined to outline specific tactical plans but emphasized that the campaign would continue until defined objectives were met. The administration has projected that operations could last four to five weeks, though officials have indicated the timeline could extend if necessary.

Rubio’s warning came as members of Congress from both parties pressed for clarity on the scope, duration, and legal basis of the operation.

Defined Military Objectives

In his remarks, Rubio reiterated that the mission is focused on dismantling Iran’s ballistic missile capabilities and degrading its naval and drone forces. He said the objective is to eliminate both Iran’s ability to manufacture and launch missiles and to prevent those capabilities from being rebuilt.

Rubio described Iran’s missile program as part of a broader strategy to shield its nuclear ambitions. He stated that regardless of who governs Iran in the future, the country would not retain the ballistic missile and drone capabilities that threaten U.S. forces and regional allies.

He also confirmed there are no active diplomatic exchanges with Tehran at this time. While he did not rule out any options, Rubio said the United States is not currently postured for ground operations and suggested that the stated objectives can be achieved without deploying American boots on the ground.

Pentagon updates released alongside the briefings indicated that more than 1,250 targets inside Iran had been struck in the first 48 hours of the operation, including command centers, missile sites, naval assets, and air defense systems.

Imminent Threat Justification

Rubio defended the timing of the strikes, asserting that there “absolutely was an imminent threat” prior to the operation. He said U.S. intelligence indicated that if Iran were attacked by Israel, it would retaliate immediately against American forces in the region.

According to Rubio, delaying action would have resulted in higher casualties. He argued that preemptive action was taken to reduce risk to U.S. service members and facilities.

The administration has stated that congressional leaders were informed before the strikes and that formal notification under the War Powers Resolution was transmitted within the required 48-hour period. Rubio said the White House complied fully with reporting requirements, while maintaining that prior authorization from Congress was not legally required .

Democratic lawmakers have questioned whether the intelligence presented substantiates the claim of imminence. Some members said the briefings raised additional questions about the long-term objective and exit strategy.

The administration’s messaging has emphasized that the campaign is preventive rather than aimed at transforming Iran’s political system.

Regime Change and Political Boundaries

Rubio denied that regime change is the formal objective of the military campaign. Although strikes reportedly killed Supreme Leader Ayatollah Ali Khamenei and other senior figures, Rubio framed the mission as limited to military capabilities.

He stated that while the United States would prefer a different governing structure in Tehran, the central aim is to ensure that Iran cannot use missile and drone forces as leverage against U.S. interests.

President Donald Trump has previously outlined four goals for the campaign, including the destruction of ballistic missile infrastructure, neutralization of naval capacity, prevention of nuclear weapon acquisition, and ending support for proxy forces

Rubio’s remarks aligned with those goals, reinforcing that the focus remains on tangible military assets rather than political restructuring. He added that Congress is free to vote on war powers measures if it chooses, but maintained that the executive branch has acted within its authority.

Broader Implications and Next Steps

The escalation warning came amid continued Iranian retaliation across the region, including reported strikes targeting U.S. facilities and allied infrastructure. U.S. Central Command has confirmed American casualties since hostilities began.

Energy markets have reacted to the expanding conflict, and the administration has indicated that measures will be rolled out to mitigate potential increases in fuel prices.

Rubio said the United States will continue operations “as long as it takes” to achieve its objectives. He did not provide a specific end date but reiterated that the next phase will involve intensified military pressure.

Congress is scheduled to receive additional briefings in the coming days, including sessions with senior defense and intelligence officials. Lawmakers are expected to debate resolutions that could limit the president’s authority to expand the operation without explicit authorization.

For now, the administration’s position is that the campaign remains focused, legally justified, and aimed at eliminating what it characterizes as a direct and developing threat. Rubio’s warning that the “hardest hits” are still ahead signals that the operational tempo is expected to increase in the days to come.
