United States Lifts Remaining Restrictions on Arms Sales to Vietnam
This report discusses the recent removal of remaining U.S. restrictions on sales of lethal weapons and related services to Vietnam.

Conventional Prompt Global Strike and Long-Range Ballistic Missiles: Background and Issues
Prompt global strike (PGS) would allow the United States to strike targets anywhere on Earth with conventional weapons in as little as an hour. This capability may bolster U.S. efforts to deter and defeat adversaries by allowing the United States to attack high-value targets or “fleeting targets” at the start of or during a conflict. Congress has generally supported the PGS mission, but it has restricted funding and suggested some changes in funding for specific programs. Some concerns that Congress has shown are the Department of Defenses' rationale for the mission, the Air Force's ability to set up the system in a timely manner, and how the new START Treaty between the US and Russia will affect the system.

On March 13, 2012, President Obama announced that the United States had joined with Japan and the European Union to bring a World Trade Organization joint dispute resolution case against China because of China's restrictive policies on rare earths and other minerals. Congress may encourage DOD to develop a collaborative, long-term, well-thought-out strategy designed to identify any material weaknesses and vulnerabilities associated with rare earths and to protect long-term U.S. national security interests.
