An armed conflict soon arose, adding to the destabilization of the region which had been unfolding through the Central American civil wars in El Salvador and Guatemala. The Contras, heavily backed by the CIA, secretly opened a "second front" on Nicaragua's Atlantic coast and Costa Rican border. With the civil war opening up cracks in the national revolutionary project, the FSLN's military budget grew to more than half of the annual budget. The "Servicio Militar Patriótico" (Patriotic Military Service), a compulsory draft, was also established.
