I am not saying anything, you're just assuming it. Civilian Government is welcome to take any initiative and give the instructions to the Army to execute them. That's another story that they lack the intellect to take any initiative, this is why they are happy to the Army take the initiative. You can't have your cake and eat it too.
Your words, its not a fact. The Army does not need to do anything, in fact the Army and the SC have been urging the Federal Government to start delivering basic governance to the people. If the Federal Government fails to deliver anything and engages in massive corruption, someone has to step in to fill the void and usually its the Army. The Federal Government is so incompetent, that they can't even implement National Action Plan.
If our history is something to go by with, it's usually true although i believe Iskandar Mirza was at fault. But look at our current Government right now, failing to deliver anything and engaging in massive corruption. Once again, the Army has stepped in to fill that void because Federal Government lacks the capacity.
You can have whatever opinion that you want, but if the Civilian Government fails to deliver on anything and leaves such a huge void, someone will step up and fill that void. Respect is earned, not given.
