They didn't die for the flag, they died for the country.
Or are we counting flags with 13 stars, or Stars and Bars, or 48 stars, or ones with snakes on them that say "Don't Tread On Me", or ...
The flag represents the country.....and as I said in my earlier post, it doesn't matter if the flag has thirteen stars or fifty, they either are or have been the flag that represents this country.
That's where flags become very, very important. It's "their flag" out on that battlefield. Not yours.
They may loan it to you but you can never own it.
Guess you didn't learn anything in school. The American Flag is the SYMBOL of America. If you can't read, maybe you can look at pictures of our GIs raising the American Flag on Iwo Jima in WWII. Or if you're not familiar with that, you may remember the WTC and the firemen raising the American Flag.
Do you know the Pledge of Allegiance?
