Okay , atleast I understand you have some understanding of the universe , happy to talk about it. You can absolutely make that argument and I agree. However, mentioning terrorism without mentioning the terrorist acts the Inserrectionists themselves has caused is disingenuous. In 2511 they killed more than 2 million alone with a nuclear device at Arcology. The information is still scarce about their size, inner working of their multiple hierchies , logistics. It's also wildly naive to assume that the prevailing Inserrectionist government that forms wouldn't end up repeating the exact same patterns of the UNSC itself, further colonizing for additional resources, etc.

Are you trying to say Halo the actual franchise itself is CIA propaganda? That's truly lazy shit at this point. You truly think the CIA is special? It's as applicable to the KGB , SVR , Mossad, Ministry of Security, British Intelligence, any clandestine agency. They're all running / have run similar operations.
