The Pentagon doesn't want soldiers in Iraq, Afghanistan, Pakistan, Iran, or other victim nations to be able to send truthful items to Americans, or to receive them, on Twitter and Facebook. For "security" reasons. Oh sure, btw, that the military will actually be able to ban these great commercial enterprises. And soldiers, think about the socialist death machine that grinds you up. Think sbout the natives, who don't want armed aliens running their countries. Come home, to those who love you. Come home, to those who will not make you wear blinders while shooting up strangers.
Chris Watson points out the irony: the US is condeming Iranians who allegedly wanted to shut down Twitter for security reasons.
