Via Rod Dreher, this 1956 Eisenhower campaign ad aimed at positioning Ike's credentials as the candidate of peace, the guy who ended the Korean War and who won't get the country into a new one:
It's an interesting counterpoint to the widespread idea that the more hawkish candidate always wins or that the United States is just an inherently militaristic country. On pretty much any metric you can imagine, the country is more culturally liberal than it was in 1956, and the objective threat level today is way lower than it was 50 years ago. For whatever reason, though, political debate is stuck in a really cramped kind of nationalism.
