Wow, what twisting. The story has changed now that "German" material has shown up.
There's no proof that this was not a US-led false-flag attack on South Korea that the US is trying to twist into that North Korea is trying to do a false-flag attack by masking a North Korean torpedo as German. Some people need to be subjected to lie-detector tests. Barack Obama should be high on that list.
Look especially at the West pointing the finger at Russia and China. With the other hand, the US will offer Russia and China carrots.
Under these circumstances, both Russia and China would be insane to back the US and Israel against Iran. [See my update in the comment section below.] The US and Israel need Russia and China more than the other way around.
