using hypnotism or using power attained by unscrupulous means and than using that power to control the world may be a thing not clearly seen by masses, so the reality is that those that we see in power such as the presidents, prime ministers and others who control this world must not allow this to happen, no one can control the masses without the permission of these rulers. So theory as noted above is just a clever theory, but if it is true than those in control are o.k. with it.
No one can do such things without being known to the Govt. of the day.
