The lesson for mediators and litigators is to work towards making a connection with every participant with whom you hope to make an ally. Physically, stand a little closer to the one who you wish to engage. Make direct eye contact. Listen and respect each varying point of view. As Lincoln famously said, ""Discourage litigation. Persuade your neighbors to compromise whenever you can. There will still be business enough."
To President Reagan's credit, he was an articulate spokesperson for peaceful transitions and stood in exactly the right place to take credit when the world events revolved in his direction. He was everybody's ally in ways that serve his diplomatic efforts incredibly well.
