Mr. Chair, thank you for the question.
That tour in Korea gave me invaluable experience, a front-row seat to what was happening in the security environment in the Asia-Pacific. What we see are countries, authoritarian states, achieving their national objectives, changing the rules-based international order to their benefit, the order that has served world security for so long and so well.
In terms of ranking threats, you've named the key ones. China, Russia, North Korea and Iran all have designs on changing either the regional or the world order for their benefit. Oftentimes, achieving national objectives just below the threshold of violent conflict by having all elements of national power work together—diplomacy, economics, military, information—is something that is of great concern.
