Also, less exposure to American news as it hits the American public?
I'd bet that a great number of people in Australia (for example) might talk trash about Trump, but vote for him had he emerged here, from their favoured party, taking a hard line on immigration, etc. We do have a political system that allows more effective voting for minor parties, but I still think he'd pick up primary votes. I know of a lot of who I would consider smart people who have very strong, negative feelings on Muslim immigration for example.
The millions of immigrants who have to leave their homes because of Hillary and Obama's failure in the Middle East probably don't want any more of that incompetence.
International treaties are a thing too - e.g. ANZUS treaty here in Australia at a time when China is sabre rattling in the region. We don't want a US president who is going to dismantle such treaties at a vital time.
So what? what does the United States care what anyone else thinks? We need to have a strong country first before we can share our prosperity. Nothing he has said is unreasonable...
So, outside of the war of Independence, can you show me a list of wars that the US has been involved in where they did NOT have any allied countries fighting alongside them? But lets just piss off all countries who have fought alongside the US in most of the conflicts in modern history anyway, because there can't be any negative ramifications, right?
Isolationist policies are great in theory. Just ask Kim whatsisname in North Korea how it is working out for him.
You're comparing "America First" to North Korean isolationism? That's not what he's saying. He's saying we need to be smart in our treaties and stop being the country that pays for everyone else. We have 20TRILLION in debt.
