Well, on public diplospeak, people don't want to tie their hands in the future with clear public statements, so they're going to deliberately say nothing while the real action happens in private. On preparation.. well, my opinion is that there are a lot of potential situations that can happen in the world, in order to have a 10-country-coordinated gameplan for every possible situation, kept up to date between the countries as governments change.. you're not going to have a script for this. What they can have is exhaustively updated briefs and intelligence on as many relevant players/interests as possible and really good communication between allies, both enabling leaders to 'wing it' as effectively as possible.
