Which nation does Les say is the one power on earth that brags about putting 200 million soldiers in the field?
China is the one power described as bragging about placing 200 million servicemen in the field. The context identifies Mao Tse-Tung's repeated claims and China's one billion population, stating it could put 200,000,000 military men on the field at any given time.
Les teaches that only one power on earth brags about this, and he points to Mao Tse-Tung constantly boasting that China could field 200,000,000 military men. With one billion people, China can put 200,000,000 servicemen in the field at any one time. He relates this to prophecy, expecting that 200,000,000-man army to be Chinese along with probably a few other Orientals, moving westward toward the Middle East, sovereignly caused by God, like Sherman's march to the sea, and eventually crossing a dried-up Euphrates.
