My entire point is that these things are seldom so black and white as put forward. The US administration has a self serving answer, but so do the French and this anonymous scientist. Which do you think is less professionally damaging for a European, being denied entrance due to views on American politics or being denied based on mishandling of classified material?
In an ideal world, I would prefer to see any mishandling of classification prosecuted, that seldom is how it works.
Without knowing a timeline, it isn't even clear which administration was running things under which events.
