The transition from one year to the next has historically been a time of celebration and hope across America. This year, however, that tradition unfolds under the shadow of heightened security concerns as major cities from coast to coast implement extraordinary protective measures for their New Year’s Eve festivities.

The timing is notable. Just one week after Director of National Intelligence Tulsi Gabbard issued warnings about threats from Islamist extremism, cities including Chicago, Los Angeles, and New York have substantially altered their security postures for what are traditionally among the most well-attended public gatherings of the year.

In Chicago, state and local officials issued a joint threat assessment in the days before Christmas. The document specifically identified crowded celebrations, including the annual New Year’s Eve fireworks display at Navy Pier, as potentially attractive targets for both domestic and foreign terrorist organizations. While officials have chosen to proceed with planned events, security presence in these areas will be significantly increased. Law enforcement will actively monitor for threats involving drones and vehicle-ramming attacks, tactics that have proven devastatingly effective in recent years both domestically and abroad.

The concerns are not merely theoretical. In Los Angeles, federal investigators disrupted what could have been a catastrophic series of attacks. The FBI successfully foiled plans by the anti-government extremist group calling itself the Turtle Island Liberation Front to target local businesses during the New Year’s period. According to authorities, the group had also planned attacks on Immigration and Customs Enforcement agents in subsequent weeks.

The severity of the Los Angeles case cannot be overstated. Members of this organization had progressed beyond planning stages and had actually begun constructing and testing pipe bombs intended for use in the holiday attacks when law enforcement intervened. One of the indicted individuals, Audrey Carroll, had allegedly sent messages to fellow members declaring, “I identify as a terrorist,” and expressing support for Hamas.

In New York City, where more than a million people typically gather in Times Square to watch the famous ball drop, a threat assessment has identified lone wolf actors and small, organized groups as the primary concerns. The assessment characterizes New York City as an aspirational target for would-be terrorists due to its symbolic significance, and specifically notes the potential for vehicle ramming attacks.

The assessment’s language is sobering in its directness. It states that lone offenders remain particularly concerning due to their ability to avoid detection until they become operational. Both al-Qaeda and ISIS, along with their supporters, continue to demonstrate interest in targeting special events within the United States, as well as American officials and other perceived enemies.

Former New York City Mayor Rudy Giuliani, who led the city through the aftermath of the September 11 attacks, expressed confidence in the New York Police Department’s ability to secure the Times Square celebration. He stated that if he were still in charge, he would proceed with the event, citing the capabilities of what he called the greatest police department in the world.

That such extraordinary security measures have become necessary speaks to the persistent nature of the terrorist threat facing the United States. As Americans gather to mark the beginning of a new year, they do so under the watchful eyes of law enforcement agencies working to ensure that celebration, not tragedy, defines the occasion.

And that is the way it is.
