In 1987, Trump made his goal of Russian collaboration on nuclear power explicit: The Soviet Union and the US should partner to form a nuclear superpower with the intention of intimidating other countries into dropping their own nuclear plans.
“Most of those [pre-nuclear] countries are in one form or another dominated by the US and the Soviet Union,” Trump told journalist Roy Rosenbaum. “Between those two nations you have the power to dominate any of those countries. So we should use our power of economic retaliation and they use their powers of retaliation, and between the two of us we will prevent the problem from happening. It would have been better having done something five years ago. But I believe even a country such as Pakistan would have to do something now. Five years from now they’ll laugh.”
Nuclear-related sanctions, from the two major powers, were to be applied to both Pakistan and France [sic]. Here is the full article, I cannot vouch for this account or any particular interpretation of it, but the hypothesis is new to me and so I present it to you as well.
