1) nuclear program was initiated by bhutto. Ìn 1974 , india detonated first nuke... That time jo koi bi pm hota program start krta.
He didn't gave atom bomb just initiated program... Nuke building is the greatest achievement of zia, who built nuke despite strong american opposition, he deceived americans by declaring the freezing of nuclear program, when two pakistani were caught red handed in usa while purchasing an alloy for nuclear bomb, bt in fack n- program was never frozen. He detonated first islamic nuclear bomb in 1985. Now pakistan had nuclear bomb bt no system to deliver it then in procured f-16 from usa.
Nuclear program was started in 76- bhutto hanged in 77 ( in this year only KRL could b built... Rather bhutto brought hurdles when he declared grass kahain gay atom bomb bunaing gay, france retreated her nuclear deal with pakistan... So it is zia who gave pakistan nuclear weapon.
Now let us look at thè darkest side...
1) quaid e awam renounced the majority of people and repudiated rule of majority in 1970 election ( 162 seats NAL vs 83 seats of ppp) and declared udhar tm idhar hum...
And put last nail in the coffin.
2. Torn apart unsc resolution on ceasefire that resulted in the ultimate fall of decca and capture of 93000 troops, that according to GC-3 n instrument of surrender india was obliged to release ...
3) lauched nationalisation - socialism when socialism was on her decline in 1970s - there were protests in eastern europe against communists yokes... Hungarian , polish , czeckoslovakia crisis... Just to break the back bone of capitalistic class against his feudal class. And nation had to pay its cost... Industrial production declined, institution over crowded due to political appointments, efficiency dwindled- and pak economy reached bankrupt status.
3) trigger baluchistan crisis when he dismissed only non-ppp govt of atta ullah mengal and lauched operation against baluch nationals.


Now if breaking of country, not accepting peoples power, demolishing economy and forcing the small province to launch separation movement are the standards of patriotism, then ZAB is the most patriotic figure in pakistan.

About imran khan my post was modified by moderator...
In history, you wil see great men are usually promiscuous eg Robert, then Lord melbourne , then Lord palmerston, and catherine, napolean had affair ,in egypt, with the wife of lieutent and a lot others yet they are the great and greatest figure in the history ... So personal life can't b attached to patriotism... I know imran khan wil not b a big success if he succeeded he can be murdered like umar bin abdul aziz yet he is far better than these demagogues.... Don't you think so?
