I want to know the answer to the following question:
What did Quasm do to anger Nasser?
All the background I'm provided with is that "Relations between Nasser and Qasim grew increasingly bitter on 9 March, after Qasim's forces suppressed a rebellion in Mosul, launched a day earlier by a pro-Nasser Iraqi RCC officer backed by UAR authorities.". Is that enough to answer the question?
