As terrorists get bolder and bolder and more delusional, it is time to give them a reality check. Terrorists can never stop and will simply move on to the next target after one disappears. For example, terrorists elements within Sunnis go after Shias if they run out of other groups to hate on.

Here are the steps.
1> There are quite a few people, especially in the US and UK, that say, "We just send money to terrorist groups to get revenge". Report these people to authorities. Money is what drives terrorism.
2> Keep an eye out for people that have uncontrolled rage against other groups out of nowhere. These are the kind of people targeted for recruiting and action. Again, watch for the word "revenge". Report them directly or anonymously.
3> Watch out for people that say that terrorists are only against government and not the people. These are the people most likely to fund terrorists. Report them directly or anonymously.
4> You are likely to hear such words mostly from friends or other that share a common religious or ethnic background. Report them directly or anonymously. Terrorists are not followers of God, they are the devil incarnate. Hateful conversations from any religious group is bad.
5> Do not donate to charities unless you are absolutely sure what they do. Donate to Prime Minister or Chief Minister relief funds when in doubt.
6> Do not carry money on behalf of others when visiting India or Pakistan. Unaccounted money often ends up in the wrong hands.
7> Do not use hawala or unofficial channels to transmit money. The underworld fanatics get a cut out of those transactions.
8> Do not do unofficial bets on cricket games. Corrupt cricket officials get a cut out of those transactions and they are tied to extortion/terrorist groups. BTW, Pakistan will have a spectacular defeat soon just to mess up the spread, now that Javed Mian gets to select the whole team.
9> Walk away from conversations that are hateful. Terrorism begins in the intelligent mind and get implemented by mindless moron. Sindhi master, Punjabi blaster. (Reference: Mad Max movies)
10> Be the possibility of peace and harmony. This is the most important step. Ofcourse, kill a terrorist before he can do harm. But be an incarnation of peace otherwise.
