True

Explanation:

It is TRUE that Roosevelt and others like him believed reinvigorated masculinity would preserve the American race's superiority against foreign foes and effeminizing effects of over civilization.

This is evident in the fact that during the Spanish-American war in 1898, the then United States President, Theodore Roosevelt and his so-called Rough Riders hold the opinion that a strong American man depicts the image of the United States as the power that is capable of its imperial purpose.
