Ah, like what details? Because I don't want the readers to be unsatisfied
Well personally the details I would want would be the responses to the attacks we just had. I mean, the TL is Korea focused, for obvious reasons, but I personally prefer a global view. Beyond that, however, how the attacks are handled domestically can have *wide reaching* effects.
I'll use your mentions of Seattle as an example, since you gave a few details there. You said a quarantine is in effect, local National Guard are out, Canada doing increased border checks, etc. This is all well and good. However, for the story to be complete, I just feel as if there's some information between "smallpox attack" and "sudden quarantine" that could have really built tension, enhanced immersion, etc. If the attack really is bad, it's a reasonable step, but I think you have to give more details on how it's bad. Yes, on an intellectual level we all know that a bioweapon is pretty freaking bad, but we're talking about 5-6 digit figure casualties. It's naturally hard for humans to grasp that scale of events. Detail is needed or else you're basically making a list not a story.
I may believe these facts but can they really do it in a quick amount of time far from home?
The way I see it is these weren't done "quickly", but had been in place for years and were just waiting for a go word or some level of event to happen before they carry out the final step.
