Washington ? In a new blueprint for U.S. defenses, the Pentagon proposes not only to build better weapons but to work more closely with other countries so they can do more to help win the war on terror.

“We know we cannot win this long war by ourselves,” Ryan Henry, the deputy undersecretary of defense for policy, said at a Pentagon news conference Friday in unveiling a 92-page defense review ordered by Congress.

The report, which takes a 20-year look into the future, will be sent to Capitol Hill on Monday with President Bush’s proposed $439 billion Pentagon budget for 2007.

The budget, representing a 4.8 percent increase from this year’s spending, eliminates no major weapons programs and includes an 8 percent overall increase for weapons, to $84 billion, for the budget year starting Sept. 30. It excludes the Energy Department’s nuclear weapons programs.

Unlike the highly detailed budget, the defense review published Friday focuses mostly on defining and diagnosing weak points in U.S. defenses, and writing a broad prescription for improvements. It reorients the Pentagon’s strategies toward the war on terror and away from conventional threats.

The Pentagon report said the wars in Iraq and Afghanistan had shown the importance of adopting a more indirect approach to the war on terror – “shifting emphasis from performing tasks ourselves to enabling others.”

The U.S. has worked with other countries before. But the move toward cooperation contrasts with what critics say was the Bush administration’s decision to invade Iraq in 2003 with a “go it alone” approach to defense and foreign policy.

One way the U.S. military would build new partnerships is to spend more time training other armies, navies and air forces, particularly in places like Africa where U.S. troops have not traditionally operated. That would require Americans to master more languages and learn more about foreign cultures.

The strategy review, known as the Quadrennial Defense Review because it is required by Congress every four years, does not alter the Pentagon’s approach in Iraq
