Namibians, no strangers to failed decolonization themselves, have thrown their support behind the Sahrawi Arab Democratic Republic. In a diplomatic reception, Namibia's president Hifikepunye Pohamba demanded resolution of the Western Sahara conflict:I therefore call on the international community to intensify efforts in ensuring that the people of Palestine and Western Sahara achieve freedom and independenceIt's nice that the Namibians, who were occupied for so long by South Africa's Afrikaaner regime, recognize the importance of self-determination.
Incidentally, there are 8 "Democratic Republics" in the world. Giving Sao Tome and Principe, East Timor, and Sri Lanka the benefit of doubt, I would say the SADR is the 4 freest Democratic Republic in the world.
