Oil and gas leasing in the Outer Continental Shelf (OCS) has been an important issue in the debate over energy security and domestic energy resources. The Department of the Interior (DOI) released a comprehensive inventory of OCS resources in February 2006 that estimated reserves of 8.5 billion barrels of oil and 29.3 trillion cubic feet of natural gas. Congress has imposed moratoria of the OCS since 1982 through the annual Interior appropriation bills. Proponents of the moratoria contend that offshore drilling would pose unacceptable environmental risks and threaten coastal tourism industries. This report analyzes this issue in-depth, including budgetary information and relevant legislation.

The FY2006 budget completed the funding required in the Shipbuilding and Conversion, Navy (SCN) account for the Navy's program to refuel and convert four Trident ballistic missile submarines (SSBNs) into cruise-missile-carrying and special operations forces (SOF) support submarines (SSGNs). Initial Operational Capability (IOC) for the program was declared on November 1, 2007. The total estimated cost of the program is about $4.0 billion.

With the end of the Cold War, NATO began to reassess its collective defense strategy and to anticipate possible new missions. The conflicts in the Balkans highlighted the need for more mobile forces, for greater technological equality between the United States and its allies, and for interoperability. At its 2002 summit, NATO approved a new initiative, the Prague Capabilities Commitment (PCC), touted as a slimmed-down, more focused Defense Capabilities Initiative (DCI), with quantifiable goals. Analysts cautioned that the success of PCC would hinge upon increased spending and changed procurement priorities, particularly by the European allies. The 2008 Bucharest summit declaration did not mention PCC, but, in light of NATO missions, particularly in Afghanistan, stressed the urgency of acquiring specific capabilities such as airlift and communications.

Perchlorate is the explosive component of solid rocket fuel, fireworks, road flares, and other products and is used heavily by the Department of Defense (DOD) and other industries. Perchlorate also occurs naturally. This compound has been detected in drinking water supplies, especially in California. It also has been found in milk and many foods. Because of this widespread occurrence, concern over the potential health risks of perchlorate exposure has increased, and some states and Member of Congress have urged the Environmental Protection Agency (EPA) to set a drinking water standard for perchlorate. This report reviews perchlorate water contamination issues and developments.

Iraq's political system, the result of a U.S.-supported election process, continues to be riven by sectarianism and ethnic and factional infighting. The Administration is optimistic that the passage of key laws in 2008, including a law to govern provincial elections to be held in early 2009, will sustain recent reductions in violence.

The U.S. Coast Guard's (USCG's) environmental activities focus on prevention programs, accompanied by enforcement and educational activities. An important component is maritime oil spill prevention, which includes inspection of U.S. and foreign-flagged ships to ensure compliance with U.S. laws and international agreements, as well as reduce the impact of oil and hazardous substances spills. Another prevention effort, minimizing marine debris, addresses commercial items as well as trash from recreational fishing and boating.

Iran is materially assisting and influencing major Shiite Muslim factions in Iraq, most of which have ideological, political, and religious ties to Tehran. Among these factions is that of hardline anti-U.S. cleric Moqtada Al Sadr, whose Mahdi Army militia, according to some observers, serves as a proxy force for Tehran against the United States.

The Department of Defense (DOD) in recent years has leased some foreign-built cargo ships for total periods, including options and renewals, of almost 10 years - a length of time that some observers argue effectively circumvents a legal requirement that U.S. military ships be built in U.S. shipyards. These observers, particularly the American Shipbuilding Association (ASA), have proposed reducing the current five-year legal limit on ship leases to two years for foreign-built ships. DOD has opposed the idea, arguing that its ship leases are the most cost-effective way to meet its needs for the ships in question.

There is no consensus definition of "middle class," neither is there an official government definition. What constitutes the middle class is relative, subjective, and not easily defined. The mid-point in the distribution is the median, and in 2007 the median household income was $50,233. How far above and below that amount the middle stretches remains an open question. This report explores the various definitions of the middle class and what salary ranges those definitions encompass, as well as related statistics and surveys that support this information.

Some in Congress have expressed concern about the government's use of private-sector lead system integrators (LSIs) for executing large, complex, defense-related acquisition programs. LSIs are large, prime contractors hired to manage such programs. Supporters of the LSI concept argue that it is needed to execute such complex acquisition efforts, and can promote better technical oversight and innovation.

China is a major source of U.S. imports of consumer products (such as toys) and an increasingly important supplier of various food products. Reports of unsafe seafood, pet food, toys, tires, and other products imported from China over the past year or so have raised concern in the United States over the health, safety, and quality of imported Chinese products. This report provides an overview of this issue and implications for U.S.-China trade relations.

The C-17 Globemaster III is a long-range cargo aircraft operated by the U.S. Air Force since 1993. To date, Congress has funded 190 C-17s for the Air Force. The C-17 program remains a key issue as Congress evaluates the needs of DOD's strategic airlift force. This paper provides program background for the C-17. For more detailed analysis of current issues regarding the C-17 acquisition, see CRS Report RL34264, Strategic Airlift Modernization: Analysis of C-5 Modernization and C-17 Acquisition Issues.

Haiti faces several interrelated challenges, the most immediate being a deepening food crisis that in April 2008 led to deadly protests and the ouster of Haiti's prime minister. Haiti also suffers from a legacy of poverty, unemployment, and underdevelopment that is compounding security problems for its new and fragile democracy. This report follows the current situation in Haiti and key legislative initiatives designed to help address Haiti's many challenges.

Financial markets underwent severe stress during the week of September 15 - 22, 2008. After Lehman Brothers declared bankruptcy and AIG received a bridge loan from the Federal Reserve, policymakers reassessed their case-by-case approach to resolving financial problems. Secretary of the Treasury Paulson announced a plan to allow Treasury to purchase mortgage-related assets from U.S. financial institutions. The announced intent of the plan is to unclog financial markets, increase the health of the banking sector, and reduce ongoing risks to the economy. This report discusses a draft of the proposal as it stood on September 21, 2008, and analyzes frequently asked questions.

The passage of the reauthorization of the North Korean Human Rights Act in October 2008 reasserted congressional interest in influencing the Bush Administration's policy toward North Korea. In addition to reauthorizing funding at original levels, the bill expresses congressional criticism of the implementation of the original 2004 law and adjusts some of the provisions relating to the Special Envoy on Human Rights in North Korea and the U.S. resettlement of North Korean refugees. Some outside analysts have pointed to the challenges of highlighting North Korea's human rights violations in the midst of the ongoing nuclear negotiations, as well as the difficulty in effectively reaching North Korean refugees as outlined in the law. Further, the law may complicate coordination on North Korea with China and South Korea.
