Here's a couple that make one really think about that doomed to repeat history thing,....
"Before a standing army can rule, the people must be disarmed; as they are in almost every kingdom in Europe. The supreme power in America cannot enforce unjust laws by the sword; because the whole body of the people are armed."
Noah Webster
"The most foolish mistake we could possibly make would be to allow the subjected people to carry arms."
Adolph Hitler
Sometimes some inspirational one's always work,...
"Blessed be the LORD my strength which teacheth my hands to war, and my fingers to fight."
Psalm 144:1
"Tomorrow's battle is won during today's practice."
Samurai maxim
I switch em' around depending on the news of the day, which since the Pres. election has really been a roller coaster of WTF? to OMG!
