It doesn’t matter if it’s intentional or merely the outcome of someone completely detached from reality.

Our thinking is still stuck in boxes marked: "America is Invincible!" "We're so BIG and Badassed no one will touch us EVER!" or stuck in the sand and we act like it.
We have forgotten Proverbs 16:18 "Pride Goeth Before Destruction, and an haughty spirit before a fall" but the reminders keep coming.
Sometimes, not always, but sometimes if you look for the message in the events around you, you can avoid what they're trying to warn you about.
One of the best "show and tells" for that message is the book Cowards by Glenn Beck.
Say what you will about the author, his book is a Must Read, scarey as hell on earth, reality check.
