On March 12, 2026, a top U.S. Army air defense expert warned that Iran could launch lethal drone strikes against California at any time, and that the West Coast’s air defenses have significant gaps.

The warnings come as the Middle East conflict continues to raise concerns about attacks on the U.S. homeland.

The White House has raised its domestic counterterrorism posture to a critical level, according to combined reporting by the New York Post and CNN.

President Trump is receiving daily intelligence briefings from the National Security Council on Iranian-linked sleeper cell activity inside the United States.

Intelligence officials are concerned that these operatives, who are funded by foreign powers and have been embedded on U.S. soil for extended periods, could bypass traditional border defenses.

The specific fear is that sleeper cell members may assemble and launch commercial or military-grade suicide drones loaded with high explosives from within California, targeting power grids, military installations, and densely populated areas.

Trump said: “I have been briefed on the Iranian sleeper cells. Many of them came in through Biden’s stupid open border policy, but we know where most of them are.”

A senior US Army air defense expert says California’s defenses have major gaps.

The New York Post cited an in-depth assessment from a top U.S. Army air defense specialist.

The expert said modern drones are small and fly at low altitudes, making them extremely difficult for traditional coastal radar networks to detect in time.

The threat is not limited to operatives already inside the country.

The expert said hostile agents could also use commercial cargo ships in international waters in the Pacific as launch platforms to send drone swarms toward the California coastline.

“Iran could use drones to carry out a lethal strike on the state of California at any moment, and we are far from prepared for the disaster that could follow,” the senior Army expert said in an interview.

The FBI is working with the Department of Homeland Security to strengthen surveillance networks covering California and other critical infrastructure sites across the country.

The military is accelerating deployment of low-altitude radar detection equipment and counter-drone electronic jamming systems, known as C-UAS, to close air defense gaps along the West Coast.

The White House has not said whether any specific sleeper cell members have been identified or located.

Officials have said federal law enforcement agencies will take all necessary steps to prevent any attack on U.S. soil linked to the Middle East conflict.
