EVA: Nod casualty rates well within acceptable parameters. Slavik: Much better. - Reprogramming EVA
After modifying the GDIEVA unit to suit Nod's needs, Slavik ordered the AI to locate the CABAL's main computer core. Destroying the core was paramount to Nod's survival, and end CABAL's mutiny. EVA found a probable location of the CABAL Core in France, where a lot of signals were emitting from that location. Slavik decided it was time to destroy CABAL for his betrayal of Kane and the Brotherhood, and tasked his commander to focus all of Nod's resources to exterminate the CABAL core.
You dare to attack me?! How pathetic! Cybernetic intelligence will always be superior! - CABAL
Just as Nod seemed to have won a hard-fought victory, the CABAL core suddenly disappeared. It actually turned out to be a trap set by CABAL, who vowed that cybernetic intelligence is superior, and launched multiple cluster missiles off-map, indiscriminantly killing all Nod and cyborg forces in the area alike.
With most of the Nod forces present at the time, the Brotherhood was hanging on for survival. By this time, CABAL had also turned on GDI after the rogue AI acquired the two pieces of the Tacitus with GDI's help. With the situation so desperate for both factions, Slavik contacted General Cortez and proposed an unholy alliance against CABAL.
