Here is an excellent essay on patriotism. The author, Robert C. Koons, explains the commonly misunderstood phrase, "My country right or wrong!" It derives from an 1872 speech by U. S. Senator Carl Schurz in which he said: "Our country right or wrong! When right, to be kept right; when wrong, to be put right." Koons is correct, as I verified for myself. See Robert Hendrickson, QPB Encyclopedia of Word and Phrase Origins, p. 538.
