Pentagon plans for potential ‘final blow’ against Iran

The Pentagon is also developing plans for a potential “final blow” against Iran if diplomatic efforts fail. Axios reported that these options could include ground operations and a large-scale bombing campaign. Trump has not yet made a final decision but is reportedly prepared to escalate if negotiations do not produce tangible results soon.

Seizing or blockading Iran’s Kharg Island

Among the options being considered are seizing or blockading Iran’s Kharg Island, its main oil export hub; capturing Larak Island, which helps Iran control the Strait of Hormuz; seizing Abu Musa and nearby islands near the western entrance of the strait; or intercepting ships exporting Iranian oil. US military planners have also reportedly prepared scenarios for ground operations to secure Iran’s enriched uranium stockpiles, though large-scale air strikes remain another alternative.

Meanwhile, additional reinforcements are already on the way, including fighter jet squadrons, Marine expeditionary units and elements of the 82nd Airborne Division.
