(CNSNews.com) - Rep. Mike Rogers (R-Ala.), the chairman of the House Armed Services Committee, asked Joint Chiefs Chairman Gen. Mark Milley on Wednesday if the United States of America is "adequately resourced and prepared" to deter and defeat a China-Russia alliance.

Milley responded that the National Defense Strategy currently is structured to deal with a "pacing threat from China and an acute threat from Russia."

"What that really means, and this changed under the former SecDef Mattis, we changed essentially from a two-war strategy to a regional contingency strategy, which (was) in existence from, I guess, the end of World War II all the way up through a few years ago."

But then, Milley said, "We switched to a one-war strategy. So we planned it to resource, train, man, equip and force-structure our force to be able to fight one major contingency against one power and to hold in the other theaters."

Milley said the shift to the one-war strategy took place in the 2017 NDS. "And I was chief of staff of the Army, we all participated in it," he said.

"Now, we can surge," Milley continued. "We would have to do that. But that's the reality.

"Our military, capability-wise, can fight in a lot of places with different types of contingencies, but if you're talking about a serious conflict, with a major great power war, realistically, putting both China and Russia together is a very, very difficult thing."
