Sure, although it requires a special kind of dedicated cynicism to not realize that technological capture of human capital with previously heinous associations, diverted toward inarguably more important scientific pursuits such as space exploration, is a net gain.
The US already had weaponized just about every other technology it had a reasonable grasp on, and had even used nukes by the end of WWII. So collaborating with former Nazis to develop peacetime rocketry for space exploration is pretty mild by comparison.
Probably worth it if you were going to buy similar products anyway, but also keep in mind you are trusting the person stored it according to recommendations. There is a big difference in actual shelf life for items stored in a cellar at consistent 18C vs. an outdoor garage that got up to 40C.
