A former Defense Intelligence Agency staffer is warning Americans that time is running out to prepare for a crisis. His post has been viewed more than 1.7 million times.

“Your window to prepare, even with the basics, is closing,” wrote Farijah “Doc” St. Clair on X. “For those tracking the indicators that an event is increasingly likely, you know that it is now undeniable that something is brewing.”

St. Clair is head of technology and intelligence at Crisis24, a GardaWorld-owned risk firm. There he leads AiiA, an AI-driven intelligence product built with Palantir that gives corporate executives a daily briefing modeled on the President’s Daily Brief. A combat-wounded Army veteran, he says he spent more than a decade in the Army and the “Defense Intelligence Enterprise,” including a stint at DIA around 2015 and 2016. His company bio says he supported efforts to counter Russian influence and deployed to multiple combat theaters.

In his post, St. Clair wrote that during his intelligence career he worked on “counterintelligence threats to Continuity of Government (COG) and Continuity of Operations (COOP).”

“Something I can say for absolute certain is that once governments signal that their citizens need to prepare, those preparations have already been conducted for national leadership,” he wrote.

He pointed to European governments urging citizens to keep supplies on hand. He also cited reports that the Pentagon wants U.S. military bases to be able to sustain themselves for 90 days, which he called “the loudest signal concerning how significant the situation is.”

“The gravity of this can’t be understated,” he wrote. “The calls for preparedness will escalate in their time frames. 3 days will turn into a week. A week will turn in to a few weeks. A few weeks into a couple months.”

His message to Americans was blunt.

“What Americans should know is that you will be on your own,” St. Clair wrote. “FEMA does not have the resources to help people in a time of need during an event at national scale. Your local authorities don’t either.”

He described a grim scenario that he said comes from an Army study of how big cities collapse when “just in time” supply chains fail.

“In 3 days, a major city is out of food in the major stores. Looting starts,” he wrote. “Suburbia is then the next harvest location. People organize and target food distribution warehouses. Then people head out into the country where people are prepared and things get ugly.”

St. Clair’s advice is to prepare, and to do it quietly.

“You, at some point, will hear, ‘well if something happens, I’ll just come to your house,’ stated as a joke. But this is not a joke. You have now become someone’s backup plan. Don’t allow this,” he wrote.

He urged readers to “randomize when you go to the store,” cut back on visible Amazon deliveries, and “start to think about how to feign poverty.”

He recommended stocking “water, rice, protein, canned foods,” along with basic medicines, and told people to watch the 1980s nuclear war films “The Day After” and “Threads.”

“We are now at the part of both movies where governments are telling people to prepare and some degree of panic is setting in,” he wrote. “This will get worse.”

He signed off with: “For everyone, hang in there. It’s going to get rough.”

St. Clair didn’t say what kind of event he believes is coming. He told readers “to not focus on the ‘what.’”

Defense Secretary Pete Hegseth has reportedly ordered U.S. military installations to become more self-sufficient, an effort covered by outlets including Fox News and the Daily Wire.
