If Americans can't protect their children from illegal drug pushers in grammar schools--they can't do anything.
If Americans can't face the truth about their elected officials, including the President of the United States--they can't do anything.
If Americans can't control their national borders--they can't do anything.
There's a big difference between the Americans of the 21st century and the Americans who stormed the beaches of Normandy--destroyed the Nazi Regime in Germany--won the Cold War--conquered polio--put a man on the moon--etc.--etc.--etc.
You stated the plain truth elegantly.
Thank you
