Explain how international-organization membership and participation in international treaties affect national sovereignty. also, consider: how is the definition of sovereignty changing in a globalized world?

Membership to international organizations have been criticized by several nationalists as it helps other countries interfere with internal decisions and policies, thereby eroding the sovereignty of such a country to act independently.
sovereignty of a nation however is a fluid concept, and with the onset of globalization international forces are forever competing with domestic interests. such areas where Sovereignty of several nations have been tested includes military practices,climate issues, energy uses, and the concepts of rights,freedoms and justice.

Good luck: )
