The killing of Hardeep Singh Nijjar in Canada earlier this year has sparked a diplomatic row between New Delhi and Ottawa. Nijjar was a Khalistani who seek to create an independent Sikh state in the Punjab region of India. They have been responsible for numerous acts of violence and terrorism over the years, and have been designated as a terrorist organization by the government. Khalistanis pose a serious threat to India's security and integrity. Their goal of creating an independent Sikh state means the dismemberment of India, which would lead to instability and conflict. Khalistanis have a history of violence and terrorism. They have been responsible for the deaths of thousands of innocent people, including Hindus, Muslims, and Sikhs. Their attacks have targeted civilians, including women and children. It is also believed that they are supported by Pakistan which has a long history of supporting terrorist groups that operate against India, and the Khalistan movement is no exception. Pakistan provides Khalistanis with financial, military, and logistical support. But Khalistanis are a threat to regional peace and stability. Their demand for creation of an independent Sikh state in Punjab has emboldened other separatist groups such as in Jammu and Kashmir. Nijjar was a key figure in the Khalistan movement. He was the head of a Khalistan group and he was carrying out an unofficial referendum on carving out a separate country of Khalistan in Punjab when he was shot. His killing will no doubt deal a major blow to the Khalistan movement. Regardless of whether the allegations levelled by Canada are true, the killing has send a message that the governments are capable of tracking down and killing even the most elusive terrorists. The killing could be a turning point in the India’s fight against the Khalistan movement. If the allegations are true, and we may never get to know the truth, the war of words between the two countries has send a message to other Khalistanis that they are not safe, and that the government is determined to crush the movement. The western countries have been left stunned by the action in Canada and many are coming after the government to “cooperate in investigation.” But the policymakers should be unequivocal that when it comes to her national interest, India is willing to cross the redlines, whether others like it or not.
