Hon Sir,
It is not a question about who is to blame. My point is that the objectives of our response/action should be to hurt or at least irritate the Modi gov't. By stopping Samjotha Express we are simply inconveniencing the Muslim & Sikh passengers. Were these travelers responsible for the repealing Article 370 or had a hand in it directly or indirectly? Why then make Muslim & Sikh passengers the target of Pakistan's anger?
However, the deed is already done. If it pleases you, I am happy for you.
