No, I don't think so.
For young men to fight well is not unique. Indeed, it's in their nature to do such things, and at the time they consider themselves immortal; it takes considerable exposure to death around them to disabuse them of that idea.
They have not done well in the area of governing, allowing the gradual slide to socialism that is now coming to a head.
I believe the greatest generation must be shared by the founders and the WWI generation.
The founders fought for a new idea, with few resources, against great odds, perservered, and performed admirably after winning.
The WWI generation fought a horrific trench war with gas and mass casualties, returned to a depression & the dust bowl, raised families in spite of it all....then gave their children to the country to face the horrors they had once faced themselves.
Fighting as a young man is easy; but then to know your sons will have to do it, but giving them to your country anyway, is greatness itself, for loving your country enough to give her that which you love most is the ultimate sacrifice.
Well said
