There's nothing new about craven appeasement
This is a cartoon from the very early 1940s, before Pearl Harbor. I was struck, of course, by its parallels to today. Change "We must be careful not to offend Hitler" to "We must be careful not to offend radical Islamists," and put the final flag as some sort of jihad image, and not a swastika, and voila! it's 1940 all over again.
