Why are American helicopter sales down

[tigershark]

I looking at the past years helicopters sales and came up with the below information.   I was wondering why the United States and France too were losing so many sales?   Being American I was surprised that the US loss the Saudi's sale and the South Korean sale, both are and have been long term US equipment users.  Suggestions welcome.
