Troops blocked off from MySpace and YouTube...

It seems that the US troops in the Middle East are no longer allowed to access MySpace and YouTube due to "security risks". The US government has banned the troops from using military computers for browsing the two well known sites as well as almost a dozen other ones.
Mostly it is reported that the troops upload videos for relatives and also watch the videos uploaded by their relatives.
However, I think this was done simply because there is SO much material on those types of sites which is Anti-war and Anti-Amerikan, footage that really exposes the futility of what those troops are doing.... and THAT is what the US commanders will not allow into the army ranks!
