Here beginneth the lesson: "If you want freedom, taken pride in your country, if you want democracy, hold on to your sovereignty and if you want peace, love your nation. Wise leaders always put the good of their own people and their own country first. The future does not belong to globalists, the future belongs to patriots."
Certainly Trump's been true to that view but whether he's made America Great Again in the eyes of the rest of the world is debatable.
Contrast that view to Ardern's and you can see why she was dubbed "The anti-Trump" in her Vogue magazine outing last year. She told those who stayed around to listen that our globalised, borderless world asks us to be guardians, not just for our people but for all people.
She posed the question, what if we change what "us" means? "Instead of fierce nationalism or self-interest, we seek to form our tribes based on concepts that can and should be universal. What if we no longer see ourselves based on what we look like, what religion we practise or where we live but instead by what we value?
Yep humanity, kindness and a sense of connection where we all look after each other, regardless of where we live, all got the tick in her well-being mix.
The difference between these two is stark which probably goes some way to explaining why an invitation for Ardern to visit the White House wasn't forthcoming this week.
Her faultless performance though slotted nicely into what the United Nations is meant to be about: united. His monotone was unapologetically about nationhood and little else.
But the reality is, a nice New Zealand, much more so than America, has to embrace the global village - it's called economic survival.
