The president has declared his intention to expand the U.S.' nuclear arsenal.
Shannon said that nuclear terrorism remained a major threat in the 21st century and countries need to work to mitigate it.
"I'm sure they won't respond well", Soofer said Thursday.
The 2018 Nuclear Poster Review released Friday notes the US military will use "tailored deterrence" to prevent aggression and attacks across a spectrum of adversaries.
Trump's strategy likewise calls for using nuclear weapons only "in extreme circumstances to defend the vital interests of the United States, its allies and partners".
"We must take into account the approaches that are now circulating in Washington and take necessary measures to ensure our security", the ministry said.
Our rivals may believe that the US would be self-deterred to respond in a conflict in which they would use low yield nuclear weapons first.
But critics warn that such low-yield weapons would actually increase the likeliness of a nuclear war because they blur the line between acceptable and non-acceptable weapons to use, increasing the risk of miscalculation.
Victims of the USA atomic bombings of Hiroshima and Nagasaki in 1945 say they fear a tragedy will be repeated.
Raising the profile of nuclear weapons in our defense plans comes at a time when the disastrous consequences of even limited nuclear use is becoming even more apparent.
The new Pentagon policy also outlines longer-term plans to reintroduce a nuclear submarine-launched cruise missile called an SLCM ("slick-em"), which the administration of President George H.W. Bush stopped deploying and the Obama administration ordered removed from the stockpile. Both China and Russian Federation are also developing new missile-defense systems, the report concludes. At the same time, the NPR notes that states like Russian Federation could use non-nuclear strategic means, including conventional and other attacks, to cripple US critical infrastructure, nuclear command and control and early warning systems.
A unsafe disconnect is emerging between the horrific impacts of even the limited use of nuclear weapons and leaders and policymakers who seem intent on threatening nuclear use in an ever-expanding range of scenarios.
Although Russia has very substantially improved its conventional capabilities over the past decade, it has not weaned itself from "non-strategic" nuclear weapons.
The US State Department said it had briefed Russian and Chinese officials on the review.
"In the nuclear context, the most significant Russian violation involves a system banned by the Intermediate-range Nuclear Forces Treaty", said the 74-page US nuclear policy report released on Friday. The treaty bans testing and fielding missiles with ranges of 500-5,500km.
The Pentagon quietly acknowledged that Russian Federation is developing a "Status-6" system for the first time ever on Friday with a 74-page report.
Although Greg Weaver, deputy director of strategic capabilities in the Pentagon, insists the US is not arms racing.
