Naval presence and deterrent reinforcement

Naval diplomacy turns the wider argument about national strength into a question of presence and deterrence. Small vessels are often best for continuous presence because repeated visits and routine policing build familiarity and friendship. The same ships may not deter a major or even medium threat as effectively as a larger vessel sent from home or from a visible distance. Navies therefore pair persistent local presence with the capacity to reinforce it using a more conspicuous force. Attempts to theorise and quantify the psychological effect remain inconclusive. The practice appears to work, even though its mechanism is still uncertain.
