I want to know the answer to the following question:
Against what government was the Hassi Messaoud defense agreement directed against?
All the background I'm provided with is that "Turning his attention to Algeria, in 1975 Libya signed the Hassi Messaoud defence agreement allegedly to counter "Moroccan expansionism", also funding the Polisario Front of Western Sahara in their independence struggle against Morocco.". Is that enough to answer the question?
