Rogue regimes, such as North Korea, continue to seek out or develop weapons of mass destruction (WMD) – nuclear, chemical, and biological – as well as long range missile capabilities and, in some cases, proliferate these capabilities to malign actors as demonstrated by Iranian ballistic missile exports.

Terrorists likewise continue to pursue WMD, while the spread of nuclear weapon technology and advanced manufacturing technology remains a persistent problem. Recent advances in bioengineering raise another concern, increasing the potential, variety, and ease of access to biological weapons.
