Why should we get affected?

One main problem that exist now in this world is terrorist attacks. The main reason that i am posting it here is, recently India is getting affected by more Bomb Blast attacks. Within two days 25 bomb blasts can you believe this. My question is, if terrorists are having problem with government means for that why should they attack the public. Why should the public get affected because of this? See the people who are giving problems are living safely under the shadows of security guards, but people here are getting affected without any reason. Each and every government should take some steps to get rid off this in future.

What you people think about this?
