英语文摘：Obama releases new security strategy, omits Bush's pre-emptive policy

WASHINGTON, May 27 (Xinhua) -- U.S. President Barack Obama on Thursday released his first National Security Strategy report, emphasizing the importance of using economic strength and diplomatic alliances alongside military power to keep the country safe and prosperous.

Obama's new strategy represents a clear break with the unilateral military approach, also known as pre-emptive strike policy, pursued by his predecessor George W. Bush through his eight-year presidency after the Sept. 11, 2001 attacks.

"The United States remains the only nation able to project and sustain large-scale military operations over extended distances," said the document. But "when we overuse our military might, or fail to invest in or deploy complementary tools, or act without partners, then our military is overstretched. Americans bear a greater burden, and our leadership around the world is too narrowly identified with military forces."

In redefinition of security strategy, the document named economic strength as one of the top national security priorities.

"At the center of our efforts is a commitment to renew our economy, which serves as the wellspring of American power," said the document, issued at a time when the U.S. is struggling to recover from the worst recession since the 1930s.
