Europe must lead the way in pushing for nuclear disarmament after Washington proposed upgrading and expanding the United States nuclear arsenal, German Foreign Minister Sigmar Gabriel said Sunday. "As in the times of the Cold War, we in Europe are especially endangered" by "a renewed nuclear arms race," Gabriel said. "That is why precisely we in Europe must begin new initiatives for arms control and disarmament," he added, according to AFP. Gabriel was responding to a so-called Nuclear Posture Review released Friday by the Pentagon that details the US militarys vision of nuclear threats and its response in the coming decades. Upgrading the US arsenal and complementing massive "strategic" bombs with smaller "tactical" weapons was "aimed at making use of nuclear weapons less likely," President Donald Trump said in a statement. American nuclear planners believe potential adversaries abroad, especially Russia, assume America would never use its existing arsenal as the effects would be too devastating. "The US and Nato require a wider range of credible low-yield nuclear options," Greg Weaver, the deputy director of strategic capabilities for the militarys Joint Staff, told reporters Friday. Gabriel acknowledged that Russias annexation of Crimea from Ukraine had led to a "dramatic loss of trust towards Russia" in Europe as well as Washington, and that "signs that Russia is re-arming, not only conventionally but with nuclear weapons, are obvious". But instead of developing new weapons, Germanys top diplomat called for "existing arms control treaties to be upheld unconditionally." Berlin would press "with its allies and partners" for further worldwide disarmament, he said. "Our long-term aim must continue to be a world without nuclear weapons," Gabriel continued - the stated aim of US nuclear policy under former president Barack Obama. Historically a close US ally and key Nato member, nuclear weapons were a divisive issue in Germanys Cold War politics.
