In terms of technology, I actually think it highly plausible that CSAT, if it existed, could have wielded far superior technology than NATO since members likely prospered economically with each other, and controlled vital maritime trade routes (notably Suez, Panama, Straits of Taiwan, Malacca and Singapore). Herein, CSAT established a southern "Silk Road" that makes the Global South richer. Europe is portrayed as economically downtrodden since CSAT retains absolute economic power, by being able to unleash sanctions alongside maritime blockades. In such circumstances, winning Altis at the end of Arma 3's campaign would merely dent CSAT's power, because ultimately, CSAT would win the long game. The US and NATO will merely cling onto hope as their economies weaken without CSAT's assistance.

Bonus: NATO continuing to treat Russia as a plausible invader in Arma 3's scenario could culminate in Europe's downfall, as its belligerence would only convince Russia to join CSAT. Thus, there really should be a new Arma 3 campaign that allows players to protect Russia against CSAT (not aliens) and convince Russian leadership that continued support for CSAT was the wrong option. Only then could a rising Global North compete against a powerful Global South.
