Pros: Harding’s presidency was overshadowed by the criminal activities of some of his cabinet members and other government officials, although he himself was not involved in any wrongdoing. An Ohio native and Republican, Harding was a successful newspaper publisher who served in the Ohio legislature and the U.S. Senate. In 1920, he won the general election in a landslide, promising a “return to normalcy” after the hardships of World War I (1914-1918).
Cons: After Harding’s death, the Teapot Dome Scandal and other instances of corruption came to light, damaging his reputation. Pretty much his reputation got destroyed when he died.

This device enabled the soldiers and the civilians to be warned about the oncoming danger, but also to be able to respond adequately to the threat.
The sonar was another invention inspired by the war. It had the same basic purpose as the radar, just that it was used for detecting objects in the water. This was a crucial instrument that gave the submarines big advantage in locating the enemy and destroying it, or if not capable of that, being able to move away and avoid it.
