Why was the generation of World War 2 called “The Greatest Generation?"

The term The Greatest Generation was popularized by the title of a 1998 book by American journalist Tom Brokaw. ... Brokaw wrote that these men and women fought not for fame or recognition, but because it was the "right thing to do."

because mexico wanted to choose a centralized location

no statements but ok.

the statement that best describes the idea of manifest destiny that was used in the 19th century would be that "it was fate that the united states would continue to  expand westward," since people thought the us was "destined" to do so.
