So no relevant experience.
No, a nuclear armed Pakistan is not a threat to US hegemony. What exactly do they have outside of the bomb that is a threat?
Iraq is not going to quickly align themselves with Iran simply because Iran has a nuclear weapon. In middle east politics today most Arab nations continue to look to Egypt and Saudi Arabia to lead them, not Iran.
Added to that, Iraq would have no need to align with Iran because as it is, the United States army is in Iraq and is protecting Iraqi sovereignty. Even if we do take your example of Iraq aligning with Iran, we will retain influence among moderates such as Kuwait, the UAE, and also in Egypt, and to an extent with the Saudi's who will turn more towards the US in effort to balance against a nuclear Iran.
In fact, there is a good argument to be made that Iran going nuclear will increase the influence of the United States in the region as more moderate arab states look for outside guarantees on their security.
You are citing a book by a journalist with ZERO footnotes and sources as your evidence? And since I assume you have read the book you can agree that he makes some bold claims in there, but strangely offers no substantiation for them. Do you take everything you read as gospel truth?
