The US military’s ability to deliver “shock and awe” on the battlefield is being overtaken by the rapidly revamping Russian and Chinese forces, the former NATO Supreme Allied commander said on Sunday.

“If you look at what’s happened over 25 years, the United States has mostly put its military modernization on . . . warm idle,” retired four-star Gen. Wesley Clark told John Catsimatidis on “The Cats Roundtable” on AM 970.

Clark, who was a Democratic candidate for president in 2004, said the United States is not spending funds on “cutting-edge” technology and that is allowing Russia and China to take the lead.

“We are spending our money on ordnance, on bombers, on missiles . . . that are blowing holes in the ground and sometimes hitting terrorists . . . But Russia — they have produced a new generation of armored forces,” Clark said.

He said Russia has developed an air-defense system that is also being used by China that will eliminate America’s ability to control the airspace.

Russia “has an air-defense system, the SA400. Four hundred kilometer range. You cannot outfly it. There’s no shock and awe where this is deployed,” Clark said. “It changes the air-ground dominance. Where the US could easily get air supremacy in the past, now we can’t.”

While the United States has been focusing on wars in Afghanistan and Iran, Russia and China are moving forward to the high-tech battleground of the future, he said.

“It’s a story the American public needs to hear . . . You need more money . . . into the defense budget on a sustained basis,” he said.

President Trump appears to be listening.

Last Thursday, Trump called for a “great rebuilding of our military might” while visiting the USS Gerald R. Ford in Virginia.

He is calling for an increase of $54 billion in defense spending — about 10 percent.
