Why does the US think the EU haven't dealt with the virus "vigorously" but the UK has?

Just that really. Banned travel from the Shengen area but not UK?

Open borders in the schengen area. As evidenced by Slovenia closing its borders. It's a salve to make people feel like he's doing something. There are open borders between the states in the US. Politics aside about Federalisation of the EU, it's just the same. Viruses don't give a shit about borders or walls etc.

Easier than drawing up a list? Alternatively it may be the case that the schengen area is already classed a ‘zone’ in their internal systems for these purposes so they’ve just run with that?

I think it was probably more politically motivated than practical. Too late anyway, there is already substantial community spread in the US.

The downfall of trump might be one of the few positives to come out of this mess.

Look at where Trump has golf courses.

Good point @DGRossetti

Italy is Schengen so if they wanted to ban flights from there they would treat all the Shenghen countries the same

I've just seen the footage of his announcement on the lunchtime news. He read the autocue wrong didn't he?

It's simply because Trump has his golf courses in the UK!

The uk have, if anything, been much more relaxed than most of Europe
