My friend, main point is facts vs. hearsay. You have confessed in one of your previous posts that you learned of the alleged nuke-sub negotiations between Pakistan and China from members of this forum and the ones from previous forum, which would lead everyone to conclude that what ever you are stating is mere hearsay. Save for one member, who does a very good research work, I take everything said here by anyone with a pinch of salt. I will, however, not jump to the conclusion that whatever you have said is entirely wrong. There may be [or not] some validity to what you have said. In fact, I'll personally not rule out that there have been discussions between China and Pakistan on this matter. The problem is the way you present your arguments makes it all sound 'outrageous.' Your assertions about Chinese exports of DF-3A to Saudi Arabia to make some sort of a point is also not helping your case since it overlooks a lot of political realities of the time when the transaction took place. China of today is not the same China it was in the 1980s. Finally, I am a structural realist myself, which by default means that I see limited potential in international laws, but I do not reject them altogether. They are less intended for rule of law and more for creating rules of engagement. Bypassing them is very likely to invite ire if not punishment but that is enough to deter even some of the powerful states.
My brotherly advice to you is, say whatever you want but weigh your words. It will generate healthy discussion, for your own benefit, and that of the others.
