All interesting.
Could they hit anything with these things? We've all seen the (played up) videos of the vaunted V-2 going up on the pad, falling over, and coming straight back down.
Was their chance of blowing themselves to bits, or glowing in the dark, or missing more than 50/50 ?
I mean would they take the chance, and I doubt they'd be able to calculate distance/direction, curvature of the Earth/winds etc., from land with maps, and even less from the water (in a sub?).
I believe the best way (even today) to rid ourselves of nuclear waste is to fire it off at the sun. They still wont do it because of the chance of it coming back down/burning up in the atmosphere etc.
Apocalyptic gamble. If they were smart enough to create this, they would've have known the risks?
I believe they still would've been strangled & smothered from outside their (newly acquired) territories from their uniformed enemies, and from within by resistance/saboteurs who dislike their uninvited company/agenda.
