Pentagon Plan to Disrupt Islamic State’s Internet

The Pentagon is working to disrupt the Islamic State group’s use of the internet, but the goal is not to “take down” the internet itself. Instead, U.S. military and intelligence efforts focus on degrading the group’s online propaganda, recruitment, and communication networks through a combination of cyber operations, takedowns of websites and social media accounts, and influence campaigns.

Formula

This calculator estimates the total volume of online content (posts, videos, accounts) that a counter-messaging or takedown operation could remove over a given period. The formula is:

Total removed = Time window (days) × Posts removed per day

• t – the length of the observation period in days (default 30).
• n – the average number of posts or accounts removed per day (default 100).
• Total removed – the cumulative count over the window.
• Removal rate – the average posts removed per hour, useful for comparing operational tempo.

All values are unit-neutral; you can substitute any unit (posts, accounts, videos) as long as you stay consistent.

Worked Example

Using the defaults: a 30-day operation removes 100 posts per day.

1. Total removed = 30 days × 100 posts/day = 3,000 posts.
2. Removal rate = 100 posts/day ÷ 24 hours = 4.17 posts/hour.

This matches the calculator output (3,000 posts and 4.17 posts/hour).

Background: What the Pentagon Has Actually Said

In 2016, then-Defense Secretary Ash Carter described the fight against the Islamic State (ISIS) as including a “cyber campaign” to disrupt the group’s command and control, as well as its online recruiting and propaganda. The U.S. Cyber Command (USCYBERCOM) has acknowledged conducting operations against ISIS’s networks, though specific details remain classified. Public reporting indicates these operations included taking down servers, disrupting social media accounts, and degrading the group’s ability to spread its message.

It is important to note that the Pentagon’s stated objective is not to “take down the internet” or to censor the web globally. Rather, the focus is on specific ISIS-affiliated accounts, websites, and communication channels. The legal basis for such operations is the Authorization for Use of Military Force (AUMF) passed after 9/11, which permits military action against terrorist groups.

How the Operations Work

Counter-ISIS cyber operations typically involve several layers:

• Account takedowns: Coordinated requests to social media platforms (Twitter, Facebook, YouTube) to remove accounts that violate terms of service by promoting terrorism.
• Server seizures: Law enforcement and military actions to confiscate or disable web servers hosting ISIS propaganda or recruitment content.
• Network disruption: Cyber attacks (e.g., denial-of-service, malware) aimed at ISIS’s own communication infrastructure, such as encrypted messaging channels or forums.
• Influence operations: Posting counter-narratives or exposing ISIS operatives’ identities to undermine trust.

These actions are often coordinated with allied nations and tech companies. For example, the Global Internet Forum to Counter Terrorism (GIFCT) was established in 2017 by major platforms to share data on terrorist content.

Effectiveness and Challenges

Measuring the effectiveness of these operations is difficult. On one hand, the volume of ISIS propaganda on mainstream platforms has dropped significantly since 2015, partly due to takedowns. On the other hand, the group adapted by moving to the dark web, encrypted apps (Telegram), and smaller platforms. A 2020 report by the RAND Corporation noted that while takedowns reduce reach, they do not eliminate the threat; the group’s messaging often resurfaces elsewhere.

Another challenge is the legal and ethical dimension. Military cyber operations against terrorist networks can inadvertently affect civilian infrastructure. Also, the line between legitimate counter-terrorism and censorship is a subject of debate. Critics argue that broad takedowns may suppress political speech, while supporters say the threat justifies the measures.

Common Misconceptions

A frequent misconception is that the Pentagon wants to “shut down the internet” or create a global kill switch. No credible evidence supports that. The operations are targeted and limited to terrorist-affiliated content. Another misconception is that the U.S. government can unilaterally delete content from any platform. In reality, most takedowns rely on voluntary cooperation from private companies, which are not legally obligated to comply with military requests (though they often do under terms of service).

Alternatives and Complementary Efforts

Besides military cyber operations, other approaches include:

• Law enforcement: FBI and international agencies arrest individuals who run ISIS social media accounts.
• Tech industry initiatives: Automated detection algorithms and human moderators flag terrorist content.
• Counter-narratives: Programs that promote alternative messages to dissuade potential recruits.
• International cooperation: Sharing intelligence and best practices through organizations like INTERPOL and the UN.

These efforts are often more visible and less controversial than military cyber operations.

Frequently Asked Questions

Is the Pentagon trying to take down the entire internet?

No. The Pentagon’s cyber operations target specific ISIS-affiliated accounts, servers, and communication channels. There is no evidence of any plan to disrupt the global internet infrastructure.

Can the U.S. government force social media companies to remove content?

Not directly. The government can request removals, but companies are private entities. However, under U.S. law, platforms must remove content that violates their own terms, and they often cooperate with law enforcement on terrorism-related content. There is also legal pressure through the National Security Letters and court orders, but those are for specific cases, not blanket takedowns.

Does taking down ISIS accounts actually work?

It reduces the group’s reach on mainstream platforms, but ISIS has adapted by using encrypted apps and smaller platforms. The effect is temporary; content often reappears. Long-term success requires a combination of takedowns, counter-messaging, and addressing root causes of radicalization.

What legal authority does the Pentagon have for cyber operations?

The 2001 Authorization for Use of Military Force (AUMF) is the primary legal basis. It allows the President to use “all necessary and appropriate force” against those responsible for 9/11, including associated forces like ISIS. Cyber operations are considered part of military force.

Are these operations legal under international law?

This is debated. Some legal scholars argue that cyber operations against a non-state actor in a country’s territory may violate that country’s sovereignty unless there is consent or a UN Security Council resolution. The U.S. position is that its actions are lawful under self-defense and the AUMF.

Why does ISIS still have a presence online despite these efforts?

Because the internet is decentralized and global. Even if a platform removes content, it can be uploaded elsewhere. Also, ISIS uses encryption and offline networks to distribute content. The takedown efforts are a cat-and-mouse game, not a permanent solution.
