Re: How to keep army away?
The only practical way can be if that ultimate punishment specified in the constitution could be carried out once or twice, then nobody will dare to use unconstitutional methods to assume power. Laikin billy kay galay main yeh ghanti kown bandhay ga ?
That won't work. All it will mean is that the next military government will refuse to ever peacefully stand down, as Yahya Khan did, and Zia's successors did.
If you know that giving up power will lead to you being killed, you will kill however many people you must to avoid being forced out.
