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.
