The Foundation supports several international solidarity initiatives, notably Palestine solidarity work across South Africa. The Foundation has spearheaded the Free Marwan Barghouthi campaign in South Africa. Marwan Barghouthi has been held by Israel after being abducted by the occupation forces in 2002. Kathrada, himself a former political prisoner, has advocated for the freedom of Barghouthi and all Palestinian political prisoners.
The Foundation continues its support for Israeli Apartheid Week, which aims to raise awareness of Israel's apartheid policies towards the Palestinians and serves to garner support for the non-violent Boycott, Divestment, and Sanctions (BDS) against Israel campaign, which seeks to bring an end to Israel's apartheid policies and violations of international law.
