To give its flavor, here’s a little item that appeared in one of the documents at Wikileaks, the one containing U.S. Rules of Engagmenet (ROE) for Iraq. The document mentioned that U.S. forces can chase suspect enemies from Iraq into both Syria and Iran. Iran’s foreign minister, Mohammed-Ali Hosseini, immediately objected: "Any entrance to the Iranian soil by any U.S. military force to trail suspects would be against international laws and could be legally pursuable," the official IRNA news agency quoted Hosseini as saying.
Of course, the United States does not bother to be restrained much by international law. But it is deeply concerned about its lawlessness being publicly bruited about. It immediately called the leak of its classified document on Wikileaks “irresponsible.”
“While we will not comment on whether this is, in fact, an official document, we do consider the deliberate release of what Wikileaks believes to be a classified document is irresponsible and, if valid, could put U.S. military personnel at risk," said Rear Admiral Gregory Smith, spokesman for the command. (all quotes from article by Bi Mingxin, Feb. 12 Xinhua, as seen on Wikileaks.)
So there you have it. War crimes or invading other countries in contravention of international law are perfectly ok to U.S. officials. But leaking the classified rules (or even documents which someone believes to be classified) which allow such crimes—that is somehow unfair and irresponsible. Brave New World anyone?
