A recent panel discussion at the Heritage Foundation on Sea Power in the 21st century. It's also available as an MP3 download.
The full rundown on who the speakers are, etc. is at the Heritage web site. One of the speakers is a blogger at Information Dissemination, where I learned about the panel discussion. It's stuff that's interesting, but not overwhelming. I especially liked their recent post on the Gates/Iran memo, which suggested to me that I probably have not yet achieved a sufficiently high level of deviousness to succeed in a political career.
