India has successfully defeated insurgencies in Punjab and the Northeast and it is now time to strengthen New Delhi's fight against insurgencies in Kashmir, columnist Sunanda Vashisht told a US Congressional hearing on Human Rights in Washington on Thursday. Terrorists trained by Pakistan had caused "ISIS level of horror and brutality" in the Kashmir Valley long before the West was even introduced to the brutalities of radical Islamic terror, Ms Vashisht said, adding that international cooperation in India's fight against terror would also solve the human rights problem in the state.
