We Cannot Seem to Shut Up
There are some things that the North Koreans and the Chinese and the Iranians (and most everybody else for that matter) just don't need to know. Take for example, all the information (all over the news, this one just happens to be a Washington Post article) about our missile interceptor tests. Their successes and their relative failures and limitations.
How about we just zip it up and play coy.
What those guys don't know might just hurt them!
