2. Political pressure and criticism: The Foundation's work often involves advocating for social justice, human rights, and reconciliation, which can sometimes put it at odds with powerful individuals or institutions.

The Foundation must navigate the delicate balance between maintaining the integrity of its historical archives and making them accessible to researchers and the public without compromising their preservation.
