Barack Hussein Obama, the former president of the USA Once said that no religion in the world is responsible for terrorism only the people who are doing those things are responsible for the violence and terrorism. Every individual on this planet is having the right to live their life peacefully, but terrorism is an act that makes the life of people hell who suffers because of it. Terrorism is the act of using violence and threat against the common civilians or the government of a country to fulfill their ideological, political, or social objectives. Terrorism has emerged as the most recent threat to international peace and, in particular, to India's national security. Terrorists are becoming more sophisticated and capable in every facet of their operations and assistance. Weapon technology is becoming more widely available, and terrorist organizations' purchasing power is expanding as a result of the ready availability of both technology and skilled personnel to operate it. Terrorists are posing a severe threat to humanity's life, progress, and development, in addition to harming democratic and freedom principles. For the prevention of terrorism, strict provisions are required. If legislation against terrorism is implemented in a country like India, it should be so strict that the perpetrator is brought to justice.
