America is facing a new generation of threats—and most citizens won't see them coming until it's too late.

Today's adversaries don't need tanks or armies. They use artificial intelligence, cyberattacks, disinformation, economic pressure, and infrastructure vulnerabilities to weaken nations from within, quietly and in plain sight.

In Know the Threat, former U.S. Army CID Special Agent Tony Perez draws on decades of experience in military investigations, corporate security, and national security to break down today's most pressing threats in clear, practical language. This isn't written for intelligence professionals—it's written for everyday Americans who want to understand the world they're actually living in.

Instead of fear and sensational headlines, Know the Threat offers real-world examples, historical context, and practical guidance to help you recognize danger before it becomes tomorrow's news.

Inside, you'll learn:

How foreign intelligence services recruit Americans

Why AI and deepfakes are reshaping the threat landscape

How cyberattacks target individuals, businesses, and critical infrastructure

What economic espionage and IP theft cost the country each year

How disinformation shapes public opinion without you noticing

Where terrorism, transnational crime, and insider threats intersect

Practical steps to strengthen your own security and resilience

This book will help you understand the threats shaping today's world and prepare you to recognize them before they reach your family or community.

National security is no longer solely the government's job. It begins with an informed, prepared, and vigilant public.

You can't defend against a threat you don't recognize. Start by knowing the threat.
