Several high profile security analysts have expressed their concerns with Donald Trump having access to the nation’s nuclear arsenal if he becomes president.

But the threat of nuclear war remains a grave concern beyond the U.S. Presidential Race; North Korea, Iran and Russia are among the many nations with nuclear capabilities that could pose a global threat in the coming future.

Ira Helfand is the co-president of the group International Physicians for the Prevention of Nuclear War. The organization won the Nobel Prize back in 1985 for helping de-escalate nuclear proliferation in the United States and the Soviet Union.

Helfand argues the threat of nuclear war remains as dangerous then as it does now.

Helfand spoke at the local chapter of the Physicians for Social Responsiblity on October 23.
