If America starts to close itself off from the world, if it engages in policies that are going to alienate its central allies, then it's a huge problem, not just for you, but for all of us. The reason why America's exceptional is because it's the most powerful country in the world, but it stands also for a set of values that are important.
And it's best those values are looked upon by people all around the world. If you turn away from what is happening in the world when those values are getting introduced and where those values are being undermined, you don't fulfill your destiny as a country. That is my honest belief.
That's why isolationism is wrong. Our duty is to stand with you. And if we stand together, the world can become a better place, right? For all its challenges and difficulties, we can overcome them. But if you're shutting away from the world, and we're left on our own without your leadership with us, then I fear for the 21st century.
