Beloved Bapuji once told: To resist Muslim atrocities by hindus using violence and intimation is tantamount to fratricide. Even if Hindus had died to a man, it would have been deliverance of Hinduism and Islam would have been purified in this land.
Government of India is just following this ideal. As long as this ideal is followed, we can expect more such terrorist acts and we need not be ashamed as we're following Bapuji's principle.
The solution is to be pragmatic. Talk Gandhian thoughts, but act like Chanakya. Be merciless while dealing with the enemies of the state.
But this is easy to say or rather write.... but difficult to follow. Just as Mr.Ram Madhav told, we need government with a will to act. Let's hope for that.
