Think V-T Day. The War on Terror is over, and we won.

What, you missed the story?

That’s because the war wasn’t won on the battlefield. It ended, well . . . in a memo from the Pentagon, to be precise.

(Oh, one more thing: The terrorists aren’t in on the deal.)

The Washington Post reports that the Defense Department’s Office of Security Review issued an agency-wide memo this week — informing staffers that the Obama administration “prefers to avoid using the term ‘Long War’ or ‘Global War on Terror.’ ”

The memo instructs all recipients to “use ‘Overseas Contingency Operation’ ” instead and to “[alert] your speechwriters.”

Overseas Contingency Operation?

That would cover tsunami relief, wouldn’t it?

And what if the terrorists blow something up in Washington, San Francisco or — heaven forbid — New York? Again?

Would that call for a Domestic Contingency Operation?

The Orwellian obfuscation originated with the Office of Management and Budget, which looks at all public testimony by administration officials in advance.

Confronted with the story, a spokesman for the agency claimed no such policy has been put into effect, insisting that the memo was merely “the opinion of a career civil servant.”

Maybe so.

But it just so happens that several administration officials — including OMB Director Peter Orszag — have been using the phrase “overseas contingency operation” for the past month or so.

Back in 2001, then-President Bush went before Congress just days after the 9/11 attacks and vowed that “our War on Terror will not end until every terrorist group of global reach has been found, stopped and defeated.”

Or until a bureaucrat writes a memo.
