The United States is commemorating the 25th anniversary of the devastating 9/11 attacks, but the landscape of terrorism has drastically changed since then. Today, the nation faces a complex array of threats, driven by rapid technological advancements and global conflicts. The weaponization of drones the exploitation of social media and the rise of artificial intelligence have all contributed to a new era of terrorism that policymakers are struggling to address.
The ongoing conflicts in the Middle East, particularly the U.S.-led war on Iran and the aftermath of the Hamas attacks on Israel have further fueled extremist sentiments. These events have not only intensified the recruitment efforts of terrorist groups but have also highlighted the vulnerabilities in the United States’ counterterrorism strategies.
The Drone Threat: A New Frontier in Terrorism
The most pressing threat to the United States today comes from unmanned aerial systems (UAS) commonly known as drones. These devices have played a significant role in recent conflicts, from the Russia-Ukraine war to the Middle East. Despite their demonstrated threat, the United States’ ability to defend against drone attacks remains inadequate.
The Federal Aviation Administration (FAA) documented over 400 illegal drone flights over U.S. airports in the first quarter of 2025 alone. The U.S. military recorded 350 incursions at more than 100 bases, and a senior Department of Homeland Security (DHS) official reported that roughly 150 drones per day were detected crossing the U.S.-Mexico border during the first half of 2025.
Despite these alarming statistics, bipartisan legislation to enhance the legal authorities for DHS and the Department of Justice to counter the drone threat has yet to be passed. This gap in response highlights the urgent need for comprehensive measures to address the evolving nature of terrorism.
The Rise of Digital Extremism
Social media has become a powerful tool for terrorist recruitment and fundraising. The self-declared Islamic State has been particularly effective in exploiting digital platforms to spread its ideology. It recruited over 53,000 foreign fighters from 80 countries, making it the first truly international terrorist group.
The digital-native generations born after 9/11 are uniquely susceptible to radicalization through social media. Sophisticated algorithms designed to engage users quickly have facilitated the spread of extremist ideologies. The Islamic State’s dynamic peer-to-peer efforts and understanding of culture and geopolitics have effectively weaponized emotions making it easier to recruit and mobilize young individuals.
The success of the Islamic State and other violent extremist groups in creating appealing content and designing narrative campaigns has set a dangerous precedent. As these groups’ skills and malleability increase, the risk of emotional engagement and interest in extremist ideologies grows.
The Iranian Menace and the Global Impact
The 2026 U.S.-led war on Iran has added further appeal to terrorist narratives. Iran has a long history of covert operations on U.S. soil, targeting dissidents and foreign enemies. The threat to former President Donald Trump and other senior U.S. officials responsible for the 2020 assassination of Qasem Soleimani has been taken seriously, as evidenced by Trump’s covert change of aircraft during a flight back from the NATO Summit in Turkey in July.
The U.S. and Israeli war against Iran should not be looked at independently. For terrorist groups that have long used the narrative that the West is at war with Islam, any war in the Middle East bolsters their argument. The wars in Afghanistan and Iraq have allowed this messaging to grow and take shape in the culture, mindset, and experience of people in the region and beyond.
It would be folly to believe the Iran war will not produce new, ideologically driven recruits intent on reprisals, including terrorism, against U.S. and Israeli targets for their governments’ 2026 campaign against Iran. Significantly, Muslim populations in every part of the world have staged protests and expressed alarm at U.S. and Israeli forces’ seemingly purposeful decimation of ancient Iranian heritage sites and civilian infrastructure and at the U.S. bombing that destroyed an Iranian girls’ school in Minab, killing 120 students.
The Role of Artificial Intelligence in Terrorism
Terrorists will increasingly exploit artificial intelligence (AI) to enhance their operations. Of particular concern is AI’s ability to identify cultural trends and even nuanced subcultures that extremists can engage with in specific ways. For instance, Islamic State affiliates are using AI to make fabricated news content seem real, with fake anchors such as those on the News Harvest show.
At the same time, governments will leverage AI’s greater resources more effectively than terrorists can to anticipate and predict terrorist activity, identify vulnerabilities, and develop defenses against emerging tactics. What is clear is that AI will intensify the technological competition between terrorists and the governments attempting to counter that emerging threat.
The United States is at risk of the same diminution of terrorism and counterterrorism as a leading national security priority that occurred in the years preceding the 9/11 attacks. Policymakers have neither prioritized nor invested in the current and future threat landscape. They have not deployed creative ideas that have been tested over the last twenty-five years to reduce the appeal of extremist ideology.
Funding for programs has dried up, and the lack of government interest in managing global coalitions to build more resilience online and offline is a serious error in judgment and a missed opportunity. U.S. policymakers need to more thoroughly assess the threat environment and what could be around the corner. This is the time to reboot their thinking about what to do right now to take easily accessible weapons away from bad actors. They should begin by launching robust efforts to deal with the seductive ideologies of hate and extremism.
