Not long ago, Trump said he would strengthen the U.S. nuclear arsenal to ensure the United States’ leading position in nuclear weapons. What do you think of Trump’s remarks?

It is a waste of money. The arsenal is already more than strong enough. The United States has 7,000 nuclear warheads. Russia has about the same number as the United States. The United States has much more sophisticated delivery systems, such as submarines. In the minds of some people in Washington, these systems should be replaced because they are getting old. Even the Obama administration was going to spend $1 trillion to recapitalize the U.S. nuclear weapons program. I don’t know how the Trump administration could spend more. So, he is just talking. It really doesn’t mean much at all.

One of the things that we are most worried about is the redeployment of tactical weapons in Asia. Former President George H. W. Bush in 1991 removed all tactical nuclear weapons from Asia. But there are people in the U.S. bureaucracy who never liked this decision. They are trying to reverse it and trying to put U.S. nuclear weapons back into Asia. We would encourage President Trump not to take their advice. The deployment of tactical nuclear weapons in Asia increases the possibility of errors, poor judgments, accidents and the chances of using nuclear weapons in a crisis.
