Between Nations Trust Is A Double-Edged Sword
Foreign policy is about security, and nations must verify before reaching a point of trust.
Think for a moment. Between nations, your government (federal, state, local) agencies (NSA, IRS etc.) or business relationships think of how important trust is when backed by historical behavior.
Make sure you are on the razors edge not the one dulled by betrayal in any form. The cut when necessary will be cleaner.
