Rolled a success! This will slow down research outside of North America, thus also slowing down thinktanks in North America. It takes longer for the race to reach a nuclear weapon that's viable is reached; one other mission with a similar goal may indeed cause World War II to not be ended through the use of nuclear weaponry, but through other, longer, probably messier in some senses means.

Please link the log for this mission here once it has been posted.
