The United States have no intention to abandon nuclear weapons, especially amid Russia's modernization of its nuclear potential, Pentagon officials said when presenting new nuclear weapons strategy.

Nuclear weapons continue to play a decisive role in deterring a nuclear attack and preventing large-scale military operations involving conventional weapons between nuclear powers in the foreseeable future, Pentagon chief James Mattis said in an introductory note to the new policy.

According to him, no American president presumes to use nuclear weapons, “except in extreme cases to protect our vital interests and interests of the allies.”

Mattis said their goal is to convince the opponents that they will not gain anything and will lose everything if they use nuclear weapons.
