Finance is a gun, politics is knowing when to pull the trigger
'The Godfather Part III' is not a great film, but it is a decent homage to Luchino Visconti's 'The Leopard'. It completes the story of Michael Corleone's life and it contains a pithy piece of political and economic wisdom.
This emerges as Vincent tricks Don Altobello into believing that Michael may be betrayed. Altobello introduces Vincent to the shadowy Don Lucchesi and this meeting of old businessman and young street hood gives us the gem.
Vincent self-deprecatingly notes his lack of knowledge of big deals and finance, but Lucchesi reassures him, saying "you know guns", and "finance is a gun, politics is knowing when to pull the trigger".
