The United States has so far endorsed more than $1.1 billion in new missile deals since it withdrew from the Intermediate-Range Nuclear Forces (INF) arms treaty agreed with the former Soviet Union in 1987, as reported by ICAN and another anti-nuclear campaign group, PAX.

"The withdrawal from the INF Treaty has fired the starting pistol on a new Cold War," head of the Nobel Peace Prize-winning International Campaign to Abolish Nuclear Weapons (ICAN), Beatrice Fihn, said.

Three months ago, U.S. President Donald Trump accused Russia of violating the treaty through a new missile system, prompting his Russian counterpart Vladimir Putin to threaten that his country would also quit the INF treaty.

"Congress should investigate the lobbying roles of Boeing, Lockheed Martin and Raytheon who took the lion's share of these contracts," Fihn said in a statement, following six U.S. companies appropriating the deals.

"What is clear is that there is a new rush towards building more missiles that benefit a handful of US companies and intend to flood the market with missiles regardless of their range," the report pointed out, noting that it is unclear if the new contracts are all for new nuclear weapon production.

Governments are signing up private companies in France, India, Italy, the Netherlands, Britain and the US for the production, development and stockpiling of nuclear weapons for at least $116 billion, the report claimed.

"President Trump is heralding the need for global denuclearisation, but US deeds, and those of nuclear-armed allies do not match those words," PAX nuclear disarmament programme manager and the lead author of the report, Susi Snyder, denounced.

"We see the US and other states planning for a nuclear-armed century, with contracts to maintain weapons through at least 2075, despite growing domestic and global calls to reverse course," Snyder added.
