Similar names granted, but definitely different.
Nothing to say that didn't get hit. Remember the strike list(s) only detail warheads of 0.5 MT or greater with only a few specific exceptions. Note also the last scout was launched in 1994 and the design retired. It also had a very small payload.
First point, with it's relative proximity to the US, and the previously established targeting of important facilities in neutral countries, do you really think this wouldn't have been hit by the Soviets?
Secondly, even if it did survive, the French are militantly neutral and not sharing anything with either side. They're not going to be launching anything for anyone (even if they retain the capability during the course of the war, which is doubtful), and they're also not going to be allowing anyone to use what little they've got already up.
Also, not only Soviet and US satellites are going to be targeted and taken out. Anything in orbit it likely to be attacked, if not by a direct strike, then by shrapnel from previous attacks. While attacks are ongoing, and until it can be deemed relatively safe, nobody's going to risk sending anything up. It's not like putting up a cheap weather balloon - these things are EXPENSIVE!!!
The Japanese aren't launching anything for the same reasons as the French. Also, during and post war (for a few years at least) they're not likely to have the raw materials and other resources to do it anyway - there's a reason why the Japanese expanded into the rest of Asia and the Pacific in the 1930's and early 40's. They just don't have many natural sources of raw materials at home.
Even if Japan hasn't been nuked (and why would the Soviets and North Koreans ignore all those US targets
https://en.wikipedia.org/wiki/United...ent_facilities), they've still got a huge (for the land size) population to try and feed. Starvation, rioting, etc would be a real problem, effectively stopping attempts at launching anything.
