IF I was in charge of the State Department (for those that don't know...the US State Department, the folks who set the visa requirements), I would eliminate all this nonsense for CREW...and continue the visa-waiver program for European/UK visitors.
Except for the 'complainers'...for these, they can wait in line for five days, if necessary.
Simply don't care.
Will the UK/EU reciprocate?
No.
For the reason that was mentioned previously...cannot get their collective act together. They simply don't have the nerve.
His Dudeness was spot on.
