I completely disagree because they clearly think themselves so intellectually superior that, if the teleporter actually broke, they could fix it.

That's the kind of stupid they are.

Well, the underground bunker used to lead to the surface and was assembled so a shaft leading up was always kind of necessary.

Teleportation just keeps people from figuring out where it is.

Yeah it was initially necessary because they didn't start off with the teleporter. And the bunker? Wasn't just a bunker. it was the original secret lab. It grew past that until they felt they no longer needed it and first sealed it off from the surface and then sealed it off from the Institute.

Even I know smart people always have a plan B. I'd use something better then a sewer though. Now that was pretty dumb. Probably a deep underwater base that leads to it.

What is really screwed up is I did the same thing to the BoS in New Vegas for the NCR that they now want to do to the Institute in Fallout 4 talk about repeating past mistakes.

On a serious note, though, that's kind of the issue of the various factions.

They're all out for each other's bloods.

I used these conversations to update my http://unitedfederationofcharles.blogspot.com/2015/11/the-moral-ambiguity-of-fallout-4.html essay, btw. Thanks to everyone here.

You gave me some great food for thought.

Slight difference between the massive Glowing Sea that's been there 200+ years, and a small, 1-block area radiation cloud at ground zero of a nuclear explosion that occured a few days in the past...

Well, it's never changing unlike, say Liberty Prime's nukes.
