Yes. Let's ban a few more countries. Are you in the military? You should stay there, and stop interfering in affairs that don't concern military. 99% of the mess we face today is because of people from your line of work. From dismemberment of Pakistan to the import of Wahabism. Kindly excel at your job, which means just do your duty of protecting the border. Leave the rest of the decisions to us. No matter how bad the politicians maybe, nothing, I mean nothing comes close to the interference by the armed forces.
I have immense respect for the Armed forces, however, it's not your place to show the civilians what to do, or even suggest such a thing. It's called Democracy, which translates to, if we as nation want to commit mass suicide, then that is our right.
Now go and submit your blue passport back to foreign office.
P.S. If you are retired for the past 2.5 years, then you are free to say whatever you wish!
