This is a great post! I did not know about Oswald, either. What a great comeback line for countering the left claims of how heroic Murtha is just because he served.
Did you also know that Oswald defected to Russia, then was allowed to come back? That's one of the bizarre factoids that the conspiracy types show "proves" he must have been working for the government. Why else would they let him into the country? As if Che Gueverra wouldn't have gotten into the country!
