Leadership is corrupt when it acts against the interests of their people to benefit their personal interests.
Swiss government is accountable to their people, not to foreigners - if they choose to act in a manner that benefits the swiss (not because it somehow directly enriches these Swiss leaders personally) at the expense of some other people exploited by their corrupt dictator, then that's not a corrupt action but a prudent decision for the benefit of their country, possibly even a duty if their people support that.
