Aliens trying to start WW3
Your A.I. is trying to start WW3 from any angle necessary, in order to cause chaos and eliminate hard targets - such as private islands.
Sounds good to the elite, since they want NWO, and are naive enough to believe in their A.I. - and are under threat by aliens.
Anyone in the background of this belligerent A.I. will be accountable for the impacts of its decisions.
You do not need to be totalitarian with A.I. and you do not need NWO. Having fragmented countries with different systems is good for global defense. It's also good for variety in culture, which makes the planet interesting for tourism.
Having one system in control of all systems is easy to hack - especially for aliens.
