Do you think India is more powerful than US or UK? Tell me one place where terrorism has been defeated with arms and ammunition.
It just cannot. When 10 Hamas men are killed in Palestine, that will be an inspiration for 30 others to join. If you want to weed out Terrorism, it is not possible for you to become a terrorist and do the job. You need to become a strategist and carefully pluck the very source out.
It has to be multi pronged. One, cut the supply of weapons and people to them. This can be done by ensuring no free availability of weapons anywhere in the world. No sale of weapons. And people can be stopped by not creating a motivation. If this has to be stopped, certain things like the Friday afternoon meetings in the mosques should be open and recorded. If needed they should play it back and show what was discussed. There should be no secrets on these issues. If they are not for terrorism, then they should accept doing this for the sake of the country and the society.
Secondly, the law enforcers should be doubly careful that they are not stepping on the other peoples shoes and they should also be careful that there are no infiltrations what so ever. This has to be strictly, very strictly implemented.
