Add to that: Repeated propagation and normalisation of fake news, I'm pretty sure it's at least partly the result of Donald Trump's influence that fake news is becoming so big in the UK. The damage he's doing to our NATO military alliance, the cozying up to Russia and Putin (and if you don't think Putin is dangerous, just think about the Salisbury poisonings), his tendency towards isolationism and the opportunities that gives to potential terrorist groups (look at the Syria pullout for example). Those are all things that potentially could cause us problems in the UK.
the damage
he's doing to the NATO alliance??
1)he has (quite rightly) stated that the US is carrying a disproportionately large share of the burden of defence..and some countries are not pulling their weight.
2) as far as europe is concerned,he wants a europe WITHIN NATO, not a breakaway faction doing it's own operations/agenda...ie not the monet plan for europe,as a counterweight(read competition) to the US.
he's basically said, right, if you want independent EU, then you fund it all yourself militarily, nothing to do with us.
3)looks like macron and merkel are doing the cozying up to putin. with germany it's obviously because of the nordstream pipeline and natural gas supplies.
4) he doesn't believe in "open doors" immigration the way the EU does, he sees it as a route through for potential terrorists.Again unpopular as it may seem, I think he will also be ultimately proven correct.
as for living in an era of globalisation, I wouldn't be too sure.
I read it as a simmering cauldron of neo nationalism brewing.
There's quite a lot of countries now taking a long hard look at the past few decades,and thinking "actually we've had quite a bum deal out of this haven't we?"
