Let's think hard...we might find answers...we know what's national interest, and we know what's not national interest. We can also infer what might be Mush's personal interest (through examples of other leaders personal interests well served in the past) and we also know what is certainly not Mush's personal interest. Lets list all 4 categories together on a piece of paper, and maybe we can draw some conclusions out of the list and judge what's what. Be sure to recall past leaders and their service to personal interests and national interest respectively.
