Telegraphing our punch?
Iran will be retaliating against the Gulf states with their short/medium range missiles. It's only natural that we would have discussed this with them, not in detail, not exact dates of attack etc. but just enough general information that's required.
Like I said, Iran know's its coming. Just like Iraq knew. As long as it's not exact operation details, it doesn't really matter at the end of the day. They can't move Natanz.
