What is the hard approach? Just look at the aggressive actions by other nations since 2K1. Those nations that acted aggressively have been reduced on a world stage diplomatically giving a rise to other nations who are not acting aggressively on the world stage. Nations acting aggressively are being shown the door by many countries who strive to be peacefull.
Let's suppose Pakistan was to take an aggressive stance today but that will ultimately fail. Why? Because of the traitors that exist in politics like tooi, taki diesel drum, 10%, anp, ptm etc. Then there are saboteurs in various gov departments to cause the state machinery damage, installed by politicians. Then there is shugal society that gets its fees paid by the western govs in the form of ngo's. Media like dawn and jang.
No aggressive stance can be taken unless cockroaches are exterminated and that is happening as we speak. For an aggressive policy your home base needs to be strong and free of radicals.
