The threats are like time bombs. You never know who would set the alarm clock and when will they blow up.
Radicals, Terrorists, and some of the Governments, are all threats to the world.
But the world is reacting slowly.
It is just like placing a large bomb in the city center. An every day scene ignored. People just forgot that there is a bomb in the city center. People forgot that the bomb is linked up with a time machine. People forgot to check whether the time machine is in the hands of a normal person or not.
There is only one reason why people choose that way:
They are too busy fighting. The Americans are fighting the Russians and the Chinese.
They do not have time, or more space in the mind to think it over.
