Re: America's increasing isolation
A few cases brought under GDPR once it comes into force and they'll give more than two hoots. They'll give some substantial fines.
I can't see that myself. I think you'll find there's plenty of cop outs in the name of security and the war on paedodruggyterroristfurreigners. And even if Germany (in particular) don't like it, are the German government really going to say "boo" to America? I think not. Particularly when they're busy hiding behind the NATO shield, whilst spending proportionately far less on defence than the US, UK or Poland.
The Mighty Orange is of course wound up about that issue of European freeloaders, so there will be pressure....but even so, any European government will eventually pony up its citizens data if asked, although I doubt that the Yanks will even bother to do that.
