You know what the critical difference between India and another country on the other side of the globe is? When people die in a terrorist attack, that country responds, because it cares for its citizens.
It is time to respond. Enough is enough. A stern warning should be given to the government of Bangladesh along with a clear choice - to either immediately hunt down the perpetrators of this heinous crime and hand them over to justice, or to face military action. As someone in this forum has mentioned, Gandhi's philosophy may have been useful in its time, but is not now. The current menace of Islamic fundamentalism is no British Empire.
