My favorite question has been on there since the beginning though.

Do you seek to engage in or have you ever engaged in terrorist activities, espionage, sabotage, or genocide?

I am always tempted by the imp of the perverse to answer yes. That genocide just sounds so inviting.

To be fair, we have had a decades long problem with European genocide-doers settling in the US. There have been regular deportations of former nazis up until just a few years ago.

There must be tens or hundreds of thousands of Europeans who have done terrorism/genocide/espionage earlier in their life and are now reintegrated into society to the point that they might want to visit Disney World.

May as well ask.

Except when they had the knowledge to work in one of several super secret government research programs.

Maybe that explains the why the question is there. They're just pre-qualifying leads for their recruiters.
