A US ship visit is something for New Zealand to celebrate, but don't be blowing a trumpet about it or the Americans might be offended.
The prospect of Kiwis thinking they have "won" the anti-nuclear stand-off is a sensitive issue in Washington.
That's why John Key was quick to say today that it was not a victory for New Zealand or a defeat for Washington but a celebration for both.
The fear of triumphalism in New Zealand may even have delayed the US from ending the absurdity of a self-imposed ban - which it will do by sending a ship in November.
Message to Washington: Almost everyone in New Zealand will be trumpeting your return for some reason.
