SEOUL, South Korea – US President Donald Trump calls North Korean leader Kim Jong-Un "a pretty smart cookie" for being able to hold onto power after taking over the reclusive Asian nation at a young age.
Trump tells CBS' "Face the Nation" television show on Sunday that "people are saying, 'Is he sane?' I have no idea."
The president also was asked about the failure of several North Korean missile tests recently and why those launches keep blowing up. Trump says he'd "rather not discuss it. But perhaps they're just not very good missiles. But eventually, he'll have good missiles."
Trump says he's not going to talk about U.S. military options because "we shouldn't be announcing all our moves. It is a chess game. I just don't want people to know what my thinking is. So eventually, he will have a better delivery system. And if that happens, we can't allow it to happen."
Trump's national security adviser, Army Lt. Gen. H.R. McMaster, says North Korea's most recent missile test represents "open defiance of the international community." He says North Korea poses "a grave threat" not just to the United States and its Asian allies, but also to China.  (AP)
