Re: appraoching, get a side...
first thing i would do would hold a nation wide referendum under a fair electoral system on banning any pakistani from
(i) holding the office of prime minister/president for more than 2 terms (in succession or otherwise)
(ii) instigating a coup (military or otherwise) against an elected parliament
results will go into the constitution, not subject to amendment, and repealable only by carrying out another referendum, requiring 90% or more votes in favor
