Last night as I was reading (still working on "The Audacity of Hope" although it's actually going quickly for a "smart" book) I came across an unfamiliar word--jingoism. I stopped to look it up then, and I'm glad I did. I've since seen the word in not less than 3 news stories today. Since it is obviously creeping into popular vocabulary here is an amalgamation of several definitions I've found:
Jingoism--chauvinistic patriotism, especially with regard to a hawkish political stance; zealous patriotism expressing itself especially in hostility toward other countries, bellicose chauvinism; flag waving.
The word was first used in connection with certain British politicians who sought to bring England into the Russo-Turkish War (1877–78) on the side of the Turks. It apparently derived from a popular song of the period:
"We don't want to fight But, by Jingo, if we do, We've got the ships, We've got the men, We've got the money, too."
So, there you are, go forth and use a new word.
