The Greatest Generation refers to those who were born during the Great Depression AND who served in WWII. Only one of your mostly insulting list qualifies by birth year but certainly not by service to his country, as David Dellenger opted for Federal prison time instead of the military. Every other person was born in the late 1930s and 1940s; Korea and Viet Nam were the wars they dealt with, one way or the other.
There is no such generation called the greatest generation, it was a phrase that Brokaw created in 1998.
Do math --- or history --- much????
If they were born at the time of the stock market crash of 1929, (not really the beginning of the depression, but just for argument's sake) they would have just be turning 16 years old when the bomb fell on Hiroshima.
Now if you want to say they were the bulk of the troops in Korea, I'll go along with you.
As for calling any generation the 'Greatest' -- I think that is nonsense.
I could make the argument right now that our 20-30 year olds fighting the WOT are the 'Greatest' because not one of them was drafted. They are all volunteers. In WWII, 2/3 of the 15 million men who served were draftees, not volunteers.
