I disagree that people will stay away. A few minutes, or an hour if you like, hassle to enter the country is a small penalty to pay for a great holiday. When all these restrictions started coming in, Mrs Jem would say 'well, shan't go there again' But we always do. We have visited the States over 20 times now, and I have never been dealt with other than with politeness, and interest by TSA people, but then, we are on holiday, and approach the booth with a smile, and a 'hi, nice to be back' Never had a problem.
Not long ago it took three quarter of an hour to get back into my home country at midnight at Stansted. Non British passport holders got through far quicker!!.
