was unavoidable. The country declared Japan as its first target. In 2014, when Russia-United States and Russia-NATO relations worsened over the Russo-Ukrainian War, the Russian state-owned television channel Russia 1 stated that "Russia is the only country in the world that is really capable of turning the USA into radioactive ash." U.S. Secretary of Defense Ash Carter considered proposing deployment of ground-launched cruise missiles in Europe that could pre-emptively destroy Russian weapons. In August 2017, North Korea warned that it might launch mid-range ballistic missiles into waters within of Guam, following an exchange of threats between the governments of North Korea and the United States. Escalating tensions between North Korea and the United States, including threats by both countries that they could use nuclear weapons against one another, prompted a heightened state of readiness in Hawaii.

In 2019, Vladimir Putin warned that Russia would deploy nuclear missiles in Europe if the United States deployed intermediate-range nuclear missiles there.
