He expressed hope for reducing tensions with North Korea   which is fast advancing toward its goal of developing a nuclear - tipped missile capable of hitting the U . S . mainland . " I do not see the divergence as strongly as some ... have interpreted it  " Mattis said . " President Trump ' s guidance to both Secretary Tillerson and me has been very clearly that we would ... pursue the diplomatic effort to include with the various initiatives with China  " Mattis told a Senate hearing .

We ' re not talking with them   consistent with the president ' s dismay about not talking with them before the time is right ."
