Former Defense Secretary Leon Panetta has issued a stark warning regarding U.S. national security, citing critical shortages in missile interceptors and munitions that he believes leave the nation vulnerable.

According to a CNN report citing unnamed sources, the U.S. military has depleted approximately 80% of its THAAD missile interceptors and over half of its Patriot interceptors. Stinger missile supplies and other key missile systems are also reported to be dangerously low.

Panetta highlighted these concerns in a recent television appearance, linking the depleted stockpiles to escalating global threats. He specifically mentioned recent U.S. intelligence assessments suggesting Russian President Vladimir Putin may test NATO's resolve within the next few years. Panetta, who served as CIA director and Defense Secretary under President Barack Obama, emphasized that such a scenario would necessitate the U.S. upholding its commitment to the NATO alliance under Article 5.

"I think we have to take this intelligence assessment as a real threat to NATO," Panetta stated. "And... we're going to have to respond. And right now, because our missile systems and our supply of weapons being down, this is a vulnerable period for the United States."

He further elaborated on the potential strain these shortages could place on U.S. military capabilities, referencing the possibility of needing to re-engage in operations in Iran while simultaneously managing Russia's ongoing conflict in Ukraine and potential hostilities from China, particularly concerning Taiwan.

"So this is a dangerous moment for the United States to have these reduced stockpiles of key weapons at a time when these threats are all real," Panetta added.

Reports indicate that former President Donald Trump expressed frustration over the weapons shortfall during a recent retreat. While Pentagon spokesman Sean Parnell has denied claims of shortages, reports from The Washington Post suggest Defense Secretary Pete Hegseth attributed the situation to his deputy secretary. Panetta, however, stated that ultimate responsibility lies with the Defense Secretary.

"Well, it should not have happened," Panetta remarked. "I don't care what excuses you want to use, it should not have happened. And I know that the secretary blamed the deputy secretary, blamed others — but frankly, the buck stops with him."

Panetta concluded by characterizing the situation as "poor planning" that resulted in the depletion of critical weapons stockpiles at a time of heightened international tension.
