Review the constitutional paradigms dictating the acquisition and subsequent administration of external geopolitical zones by the Indian Republic:
1. The formal integration of any newly acquired foreign landmass strictly necessitates the immediate passage of a Constitutional Amendment Bill.
2. The acquisition process relies predominantly on established modes recognized by international jurisprudence, such as diplomatic treaties or sovereign purchase.
3. The administrative and governance frameworks initially applied to these newly integrated zones mirror the constitutional protocols designed for Union Territories.
