Not Japan- we have never deployed nuclear weapons on Japanese soil. From 1954 to 1972 we had nuclear weapons on Okinawa but they were removed in 1972 when Okinawa reverted to Japan. Is Japan going to reverse its policy of not allowing nuclear weapons on their soil? If so, which does not seem likely, they would probably develop and deploy their own systems since they have the technology to do so and enough plutonium for 5000 warheads.
Not South Korea- we removed our nuclear weapons from there in 1991. Some Korean “hawks” have discussed the possibility of allowing the US to again deploy tactical nukes on their soil but either the current government nor the preponderance of the South Korean people want them.
NATO countries? Not likely.
“Oliver Meier, the deputy head of the international security division at the German Institute for International and Security Affairs, said: “Trump’s sudden decision to terminate INF puts Germans in a difficult spot. Most see Russia as being responsible for the INF crisis but do not understand what Trump hopes to achieve by withdrawing from the treaty.
“There is a fear that in a post-INF world, discussions among Nato allies about appropriate military responses to Russia’s actions would become more difficult,” Meier said. “There is little faith that deployment of additional ground-launched cruise missiles would convince Russia to come back to the table. All of this would play into Putin’s hand.”
“The decision to withdraw from the INF has been widely criticised as a mistake by US nuclear experts, who say it will benefit Russia more than the US, arguing that Russia will now be unshackled in its development of short- and medium-range ground-launched nuclear missiles, while the US is unlikely to find allies willing to host such missiles on their soil.”
They say the same goes for the Pacific, where China’s development of medium-range missiles has been cited as one justification for freeing the US from the INF’s constraints.
“Thirty-five years ago, the United Kingdom, West Germany, the Netherlands, Italy and Belgium agreed to deploy 572 nuclear-armed U.S. ‘Euro-missiles.’ None of them appear willing to accept them now,” Michael Krepon, co-founder of the Stimson Centre thinktank and a veteran writer on nuclear weapons issues, wrote on the ArmsControlWonk blog.
