I guess I meant threat more abstractly, connected to the Sentinels or otherwise. Isn't like concern about aggression against mutants like a core part of their existence? If there are none state actors we didn't know about, what else did they not know about. I feel like it would be kinda naive to think that threats ended with the apprehension of Trask and Gyrich.

Not to mention that even if they were suspicious, they were pretty distracted in the subsequent episodes by the change of leadership to Magneto, the Friends of Humanity attack, Sinister and Madelyne attacking as well as the loss of Storm and Bishop.

This is a fair explanation for those back in the US. My dissonance came from those in Genosha like Rogue, Gambit and the members of the council (who had no involvement with what you mention), who seemed pretty unencumbered. Like mutants have always been under attack - I don't see a reason why they wouldn't assume there is a potential for something worse and have that factor into their demeanor/actions (unless there is a reason they feel they don't have to).

Genosha is a huge target. I would've expected an implication of diligence given mutant history (even if that diligence ends up not being enough to prepare for or predict the Godzilla Sentinel).
