From Green Eagle:
The United States did in fact destroy about 1,000 nuclear missiles after this treaty was signed (the Soviet Union destroyed about 2,000.) But other than the financial loss, the treaty meant little to us because our supposed enemies, the Soviet Union and China, were well over 5500 kilometers from our missile bases, which were located in the middle of the United States.
The situation for the Soviets, however, was considerably different, as can be seen from a glance at this map …
In fact, the forbidden range for Russian nuclear missiles includes virtually all of Europe. And that is the point:
The U. S. abrogation of this treaty will allow Vladimir Putin to deploy nuclear missiles targeting the entire continent of Europe.
Let the NATO nations try to stand up to Russia then.
