JKP..you miss my point...we can and we do study about other countries and make reports to concerned departments for our internal use. So does USA, Russia, UK,China and every one else. No one can stop others from making a study about something or some one . We need to react if and only if they intervene in our activities and ask us to change our policy. Eg.US intervention in Iraq cannot be accepted. When we cannot do something about it, it is better to leave it at that.
