Lets not oversimplify the issue. The connotation for an "Islamic Bomb" has certain negative implications for Pakistan and lets not pin the blame for this on Pakistan because not a single Pakistani leader has gone on to boast of this capability as a "Islamic bomb" ever since we first acquired it in 82. Since a "zionist" or a "hindu" bomb is essentially for the security of the above two entities which happen to be countries, the term "Islamic bomb" can be taken by some to mean that Pakistan would use it around the world or would be open to giving it to anyone who happens to be a Muslim. This is the scare that the anti-Pakistani lobby thrives on.
ZABs comments should be taken in light of the western nuclear apartheid. Why should a Muslim country such a Pakistan or for that matter, Egypt, Turkey, KSA not be allowed to have this capability when every other major power has it? While one can debate about the supposed "secularity" of the Indian bomb, at least the Israeli bomb can fit the same bill as a so-called "Islamic" bomb.
