The main purpose of this legislation, titled the "No Mercy for Terrorists Act of 2026," is to strengthen the penalties for individuals involved in terrorist activities in the United States. The goal is to deter terrorism by imposing harsher consequences for those who provide support to terrorists or engage in related activities. Key provisions of the law focus on increasing the penalties for two specific offenses. First, for individuals who provide material support to terrorists, the maximum prison sentence is raised from 15 years to a minimum of 20 years or life imprisonment.
