Latin American leaders across the political spectrum praised President Obama's announcement on Wednesday to reestablish diplomatic relations with Cuba, a move that could spark more investment in the Caribbean island and ease Cold War-era resentments throughout the hemisphere. Hours after the announcement, the Colombian guerrilla group known as the Revolutionary Armed Forces of Colombia, or FARC, declared from Havana a unilateral and indefinite cease-fire as part of ongoing peace talks hosted by Cuba. From Venezuela to Mexico and Colombia, Latin Americans welcomed in glowing terms the thawing of relations between the decades-long rivals.
