How can supranationalism challenge sovereignty?

Supranationalism in my view (not a scholar) is a superior category in the international relations system. Supranationalism takes simple inter country relations between countries and applies them to various countries in an unified manner. Should one country decide it is not in their interest to develop a relationship with another entity, it will not develop it. In the same way, should a country decide it is in their interest to enter in a series of treaties, the country can decide to enter and follow all the rules the treaties enforce.
