Comprehend

"If America is destroyed, it may be by Americans who salute the flag, sing the national anthem, march in patriotic parades, cheer Fourth of July speakers -- normally good Americans, but Americans who fail to comprehend what is required to keep our country strong and free, Americans who have been lulled away into a false security."
--Ezra Taft Benson (1899-1994)
President of The Church of Jesus Christ of Latter-day Saints
