Clinton-era redux.

WASHINGTON — Cuts to defense spending in the debt reduction bill could total nearly $1 trillion over 10 years — more than double what President Obama had proposed earlier this year — and sap American military might worldwide, say analysts and members of Congress.

Budget cutters may have to consider slashing costly defense systems like the U.S. military’s replacement fighter jet or increase health-care premiums for working-age military retirees to comply with a debt reduction deal that may cut as much as $900 billion from the U.S. military over 10 years.

“They could do this responsibly,” said Todd Harrison, a budget expert at the Center for Strategic and Budgetary Assessments. “The reality is that it will be very difficult.”

Thomas Donnelly, a military analyst at the American Enterprise Institute, said the Pentagon cuts won’t require “long knives so much as chain saws.”

Harrison estimates the reductions in defense spending could rise to $900 billion over 10 years.

The proposed cuts would force critical weapons systems to be trimmed or eliminated along with reductions in military personnel and training while at war, Donnelly said.
