This statement provides extensive detail about numerous state and nonstate actors, crosscutting political, economic, and military developments and transnational trends, all of which constitute our nation's strategic and tactical landscape. Although I believe that counterterrorism, counterproliferation, cybersecurity, and counterintelligence are at the immediate forefront of our security concerns, it is virtually impossible to rank—in terms of long-term importance—the numerous, potential threats to US national security. The United States no longer faces—as in the Cold War—one dominant threat. Rather, it is the multiplicity and interconnectedness of potential threats—and the actors behind them—that constitute our biggest challenge. Indeed, even the four categories noted above are also inextricably linked, reflecting a quickly changing international environment of rising new powers, rapid diffusion of power to nonstate actors and ever greater access by individuals and small groups to lethal technologies. We in the Intelligence Community believe it is our duty to work together as an integrated team to understand and master this complexity. By providing better strategic and tactical intelligence, we can partner more effectively with other Government officials at home and abroad to protect our vital national interests.
