Defense Secretary Leon Panetta warned Thursday he would not accept large military cutbacks under a debt deal, charging the move would weaken the United States faced with rising powers.
Panetta, holding his first formal news conference since taking charge of the Pentagon a month ago, launched a pre-emptive strike as a special committee prepares to slash spending under a last-ditch deal to avert a US debt default.
Panetta, a veteran Democratic Party dealmaker who was once in charge of budgets, said that "God willing" the process would not trigger sweeping cuts under which the Pentagon could lose another $600 billion.
Such cuts "I believe would do real damage to our security, our troops and their families and our military's ability to protect the nation," Panetta said.
"It is an outcome that would be completely unacceptable to me as secretary of defense, to the president and, I believe, to our nation's leaders," he said.
Defense spending, which has nearly doubled since the September 11 attacks a decade ago, accounts for 20 percent of the federal budget. The United States spent some $700 billion last year on defense, far more than any other country.
