Honestly, I'm indisposed to trust the Pentagon. It is obvious that the White House tries to through dust in the eyes to make the world think that Americans only develop conventional weapons, when we know it is bullshit. All this fuss about MOP is only a cover to developments of newest types of nuclear weapon and baby nukes that are supposed to be used against Iran.
Why do Americans need to hammer Iran with nuclear bombs? Oh, it is plain as day. Americans plan to give the after-effect of bombing (which is nuclear pollution, of course) out for an evidence to adequate choice of targets, which must be Iran's "nuclear weapons production facilities" that do not exist in actually.
Over again, the US tries to fool the world just the way it was done in Iraq.
