Unfortunately, Mr. Chapman sees a world where the bad guys are only minor players that can't harm the U.S. or our "protected allies"! Mr. Chapman lives in a dream world! I realize that he is probably a Libertarian, I share some Libertarian ideals too, especially about not looking for wars to start around the globe. However, Mr. Chapman's view of our potential adversaries, and their strengths, weaknesses, and abilities and to harm us or our friends and allies is naive and dangerous.
Mr. Romney is exactly right; we DO live in a dangerous world where mistakes can be fatal, and unforgiving. Mr. Romney realizes that many Countries don't like or admire our freedoms, and seek to diminish U.S. influence around the world.
