Shortly after leaving the hacienda, Mitchell receives word from Keating that U.S. President Ballantine and Mexican President Ruiz-Peña finally signed NAJSA, effectively allowing the United States to assist Mexican Loyalist in putting down the insurgency in Juárez and the rest of Mexico. Assisting a second team of Ghosts designated as Bravo Team, U.S. forces and the Ghosts uses the rescued journalist's information to begin tracking down the two missing nukes, yet despite killing de la Barrera in the process, they only manage to retrieve and neutralize one of the remaining nukes. Concerned about where the last nuke went, fresh intelligence reveals that the mercenaries launched an attack on a dam within El Paso, Texas, prompting fears that the nuke will be detonated upon U.S. soil. However, Barnes reveals that the mercenaries' target was actually a highly classified military installation beneath the dam, code-named "Farrallon", that is connected to the United States anti-ballistic missile defence grid. Keating pieces together what de la Barrera was planning - by dropping the grid, he intended to use the stolen missiles to launch the nukes into the United States and any of its major cities, in the hopes it would force them out of Latin America.
