Ok but those bunkers are packed with resources that we could make (much better) use of. No sense welding those in too. We've got to flush them out and raid their hoard first.
Remember this sentiment if/when SHTF.
Fascists may be an immediate danger, but they ultimately serve as a distraction & shield to protect the super-rich. Map their bunkers. Strike the root.
I mean, we (the proles) made their bunkers right?
