The essential part of a state’s national security lies in how it manages the dynamics of the use of force — its defense capability.

At the core of this defense capability is the defense equipment that guarantees the fundamental functions of national defense — including preventing, deterring, coercing and countering national security threats — and solidifies diplomacy to create a desirable national security environment for a country.

In 1901, weeks before becoming U.S. president, Theodore Roosevelt outlined his ideal foreign policy in a speech using the phrase “speak softly and carry a big stick,” indicating the idea that active diplomacy would be possible only through carefully mediated negotiation supported by the ultimate guarantee of defense power.
