According to Comey, ISIS has influenced a “significant number” of Americans through a year-long social media campaign that urged those Muslims who can’t travel to the Middle East to “kill where you are.” The FBI Director acknowledged that the group has more than 21,000 English-language Twitter followers worldwide, and that the FBI has arrested or detained a significant number of people over the last few weeks who had been radicalized.

When asked if the threat the Islamic State poses to United States security had eclipsed that of Al Qaeda, Comey simple said, “Yes.”

This news isn’t exactly shocking. ISIS has inspired dozens of Americans to travel to Iraq and Syria to fight alongside them, and the number of radicalized, ISIS sympathizers continues to grow on a global scale.

Comey said that Islamic State is a bigger threat than Al Qaeda because the type of person ISIS is willing to recruit is very different. Al Qaeda doesn’t want drug abusers or mentally deranged individuals, but ISIS isn’t as selective and often targets those that are unstable.

“I worry very much about what I can’t see,” Comey added, because he said ISIS recruiters use encrypted communication software to avoid U.S. eavesdropping.

Comey also said that it was too early for the FBI to determine how Muhammad Youssef Abdulazeez, the Chattanooga gunman that killed five U.S. troops last week, became radicalized and if he was attached to a group.

Do you remember last year when ISIS was really gaining a stronghold in Syria and Iraq and the Left mocked conservatives who were worried about the threat ISIS posed? I remember being mocked openly from people saying that ISIS was just a group of “poor, uneducated, slobs who aren’t sophisticated enough to worry the United States. Once again, Leftists were dead wrong about an issue.

Radical Islam is a huge and growing threat to the security of the world, and with Iran sponsoring terror abroad, the threat only increases. It’s time to wake up, or more attacks will occur on U.S. soil.
