Before I could enter USA as EU citizen, I had to register via VWP in 2005 and 2006, got interviewed/screened (including my fingerprints taken) by airline as well as border control (fingerprints only by border control). As part of VWP, I had to state I did not take part in WWII on the Axis side, etc etc (I was born in the 80s...). I'm not sure what the requirements of Americans entering Europe were or are, can't imagine they were/are as strict. Going back, guy looked at my face 2 times, and I was allowed in. Its nice living in a free country like The Netherlands, I thought. And yes, we did have terrorism threat back then (Muslim extremists).
