Just as it establishes the preamble of the Law of the National Defense, the Republic of Cuba and its politics is based for the national defense on its aspiration of a worthy, true and valid peace for all the States, settled in the respect to the independence, sovereignty and self-determination of the peoples, as well as in its commitment of completing the other principles proclaimed in the Letter of the United Nations and in other international treaties of which it is part. This is the base in that the military politics of the Cuban State is sustained.

The aspiration to preserve the peace is permanently threatened by the possibility of a military aggression of the United States. This is as real as the existence of the economic blockade and of the tenacious political war, diplomat and propagandistic that the main world power develops against Cuba for more than four decades. The superiority in troops and the proximity to Cuba of the only potential enemy's armed forces, next to that declared opponent's possibility of maintaining naval military groupings in the vicinity of the Cuban coasts and the existence of a North American Naval Base in Guantánamo, oriental end of the Island, against the apparent will in the urns of the Cuban population's immense majority, are, among other, the causes that have forced to the peaceful and friendly Cuban people, without conflicts of any type with any other country, to develop solid defenses.

The "Guerra de Todo el Pueblo" is the strategic defensive conception of the country that summarizes the historical experience accumulated by the nation. It is based on the unfolding of the territorial defensive system as sustenance of the military power and in the employment of all the forces and resources of the society and the State. If Cuba is victim of an armed aggression in great scale, all citizens will have a means, a place and a form to participate in his rejection.

In terms of operative calculations, the correlation between the Revolutionary Armed Forces and the only potential aggressor is overwhelmingly in favor of this last one; but the same as in the last fights for the independence, the fairness of the cause and the high morals of the people sustain the firm conviction that the country will never be defeated. To be strong militarily means, for Cuba, to avoid the war. It is a deterrence element in front of the enemy; it consists, above all, in guaranteeing the peace, the deepest desire in all the Cubans.
