A tungsten rod placed in an eliptical polar orbit can be pointed to any point on earth fired without anyone detecting it, and have total plausible deniability when wiping a city off a planet. We're far more likely to have destroyed ourselves long before we get a chance to destroy any other civilisation. If we can travel intersteller, we can destroy a planet. Your quote does remind me of a line from Independence Day I like "Los Angelinos are asked not to fire their guns at the visiting spacecraft, you may inadvertently start an intersteller war"
