I'm not saying they're lying. Just that they haven't provided any evidence to us, while the circumstances so far has leaned towards American involvement. I believe that one or more of the attackers said they did it for money, and that it was paid to them via card, so those two things are the only public record we have so far of a non-religious entity involved. Obviously they're not going to show anything during an investigation, but I'll reserve my judgement until something more concrete is shown. Someone here made a compelling case of Ukraine going rogue and the US "warning" ahead of time because their plans are in conflict with each other.
