Supporting Bolivian revolution
- The democratically elected government of Bolivia's first indigenous president Evo Morales Ayma, which is heading a process of democratic change, is Washington's immediate target in Latin America today. Bolivia is in Washington's sight, not only because it is viewed as the weakest link of the growing axis of hope in the region, but because of its role as a catalyst for inspiring the struggles of indigenous peoples, regionally and internationally, for real social justice...
- Now is the time for all intellectuals, union militants, solidarity activists, political parties and progressive minded individuals who believe in real justice and equality to raise their voices in defense of the Bolivian government and its people. No to US interference in Bolivia!
