It's heartening to see so many Americans protesting about this ban in the streets of many cities there. And I see that Trump has changed his 'edict' with regard to visitors from the UK with dual nationality. He doesn't seem to know what he's about does he? He looks a bit silly now, having to go back on his initial ruling.
I think a State Visit should be deferred for a few months until we see which way the wind blows. Things are already looking a bit wonky in my view.
