The Russian government is regarding U.S. moves to increase and upgrade its low-level nuclear arsenal as a sign that the White House is prepared to use nuclear weapons as a political option on the world stage.\u0022Washington is not just modernizing its nuclear forces, but is striving to give them new capabilities, which greatly expands the likelihood of their use,\u0022\u0026nbsp;Russian Foreign Ministry spokeswoman Maria Zakharova said Friday.\u0026nbsp;Zakharova told reporters that the U.S. increase in nuclear weapons capabilities earlier in the year, when the military deployed a low-yield ballistic warhead to its submarines, reduces the threshhold for using the weapons and brings the world closer to the possibility of nuclear war. As\u0026nbsp;Common Dreams reported, the move was seen by International Campaign to Abolish Nuclear Weapons treaty coordinator Tim Wright as\u0026nbsp;\u0022an alarming development that heightens the risk of nuclear war.\u0022\u0022Of particular concern is the expansion of the range of U.S. low-yield weapons in its nuclear arsenal, including the development and deployment of such munitions for strategic carriers,\u0022 said Zakharova.The U.S. in February angered Russian officials for a war game in which the Pentagon ran a scenario where Russia attacked a NATO ally with a low-yield nuclear weapon and the U.S. responed with a \u0022limited\u0022 nuclear strike.\u0026nbsp;According to RT, the Russian government\u0026#039;s concerns are based in part on the U.S.\u0026#039;s nuclear doctrines:Unlike Russia, the U.S. never made a formal commitment not to be the first to use nuclear weapons in a conflict. Russia\u0026#039;s nuclear doctrine says it may use nuclear weapons in response to a conventional attack that threatens the existence of Russia as a sovereign state, but otherwise the nuclear option would only be used in response to an attack with weapons of mass destruction.As the\u0026nbsp;Washington Physicians for Social Responsibility\u0026#039;s Bruce Amundson and\u0026nbsp;Joseph Berkson wrote for the\u0026nbsp;Seattle Times in February after the U.S. deployment of low-yield weapons was announced, the deployment raises the risk of overreaction and escalation:To an adversary, a submarine-launched missile with a low-yield nuclear warhead would likely be completely indistinguishable on radar from missiles armed with high-yield bombs. Therefore, an adversary may respond to such a launch with a full attack, immediately escalating the conflict to full nuclear war. This dramatically increases the chance of a nuclear exchange due to miscalculation or human error.In her remarks Friday, Zakharova said Moscow was treating U.S. moves as a sign the country \u0022has made a decision to consider a nuclear conflict as a viable political option and are creating the potential [scenario] necessary for it.\u0022President Donald Trump and his administration have been\u0026nbsp;reluctant\u0026nbsp;to commit to renewing the Nuclear Nonproliferation Treaty in April 2021. The treaty turned 50-years-old on March 5, leading United Nations General Secretary\u0026nbsp;António Guterres in a statement to call on treaty signatories to recommit to world peace.\u0022The Secretary-General calls on States parties to make the most of this opportunity to strengthen international peace and security through the promotion of non-proliferation of nuclear weapons and nuclear disarmament, as well as measures to strengthen implementation of the NPT and achieve its universality,\u0022 said Guterres.
