The monument was constructed in honor of the young Mexican cadets who lost lives defending national sovereignty from U.S. invaders. The ceremony was of great significance because in 1955, in front of this same monument, Fidel Castro, who was then in exile in Mexico, vowed he would someday return to this historical site after attaining true independence for Cuba. After the ceremony to honor the Hero Children of Chapultepec, the highest Cuban leader reaffirmed to reports that Latin America has no alternative but to search for its unity and integration. Fidel Castro said any step by Mexico or any other country in the area seeking to solve the foreign debt problem would be very positive. However, Castro insisted the ideal would be a joint action by all nations in the region. The Cuban president has been in Mexico since 30 November, for the inauguration of President Carlos Salinas de Gortari. -END-
