And where the heck is Degelen Mountain, anyway? In the Altays by China? Or in Tian-Shan along the south, by Taraz, Almaty, or Shymkent? Or is it just some hill somewhere in the vastness of Central Kazakhstan?

Its very unlikely that the US would refuse to permit a puchase of 10% of Westinghouse, equity, which after all does not imply any change of control.

Official US statement, May 26, 1995:

“The United States warmly congratulates Kazakhstan on becoming a state free of nuclear weapons. On April 21, the last nuclear weapon was removed from Kazakhstani territory. Kazakhstan has fulfilled its pledge to become a nonnuclear weapon state under the nuclear Non-Proliferation Treaty (NPT) . It ratified the NPT during Vice President Gore’s trip to Almaty in December, 1993. This is a very significant accomplishment for Kazakhstan, for the United States, and for the cause of non-proliferation, which is one of this Administration’s primary foreign policy concerns.”

What happened in Kazakhstan in 1991-1995:

“Subsequent to its independence, Kazakhstan found itself owner of one of the world’s largest nuclear arsenals. The weapons of greatest concern were the 1,400 nuclear warheads on SS-18 ICBMs that remained in Kazakhstan when the Soviet Union disbanded. Kazakhstan also had 40 Tu-95M long range bombers equipped with 320 cruise missiles.

All nuclear weapons were out of Kazakhstan by May 1995. Kazakh disarmament activities included:

* return of 1400 strategic nuclear warheads and 104 SS-18 ICBMs, as well as their support equipment to Russia;
* eliminating 147 ICBM (mostly SS-18) silo launchers, launch control centers and test silos located at Zhangiz-Tobe, Derzhavinsk, Semipalatinsk and Leninsk;
* closing and sealing 178 of 181 nuclear weapons test tunnels at the Degelen Mountain Test Tunnel Complex and 13 vertical test bore holes at Balapan;
* dismantling 7 heavy bombers.

Before the dissolution of the Soviet Union, Kazakhstan was the most significant site of military-industrial activity in Central Asia.
Chemical and biological weapons were produced in Aksu, and chemical weapons were manufactured in Pavlodar. By 1994 most of Kazakhstan’s defense plants had ceased military production.”
