Excuse me but don't you get it. We don't have a need to know! As long as we and our kids can go to bed not worrying about this nonsense then were save and sound.
Whenever we release this info it aids the enemy and that ain't such a good idea.
It also gives another reason to point back to when we attack Iran. They have been building up these last few months, almost as if intentionally - as if a case is being made.
