Kerry cautioned that a new arms race was taking place and endangering other weapons reduction treaties.
Kerry spoke on Tuesday in Milan, ahead of Trumps planned announcement on whether to pull America out of the nuclear deal between Tehran and world powers.
Kerry told a conference on food innovation that dangerously, we find ourselves today with certain individuals who are talking about a new arms race, and that the money it will cost should be going to health and going to building schools and going to building infrastructures and building the future, instead building weapons.
He said the moves were putting at risk both the Intermediate-Range Nuclear Forces Treaty and the Strategic Arms Reduction Treaty that ended the U.S.-Soviet arms race.
