On 21 October 2025 Russia conducted "the key test" of the Burevestnik nuclear-powered cruise missile (also referred to as SSC-X-9 Skyfall). The test is reported to be successful. The missile travelled 14,000 km in a 15-hour flight (Image: Pan'kovo test site). Links follow 1/

Climate change & nuclear weapons are often seen as twin threats to future generations. My new open access article shows that while both pose similar moral dilemmas, intergenerational nuclear injustice is harder to spot—and harder to fix.

To be sure, I'm not saying that Russia did not violate INF Treaty, my points are:
- calculation of maximum theoretical range of a CM is not a correct way to determine its actual maximum range;

bsky.app/profile/kady...
BM and CM are very different beasts. Why do you think GLBM range is defind as “range,” while GLCM range need to be ”determined by projecting its flight path onto the earths sphere from the point of launch to the point of impact."?

I'm sorry, but the arguments in this thread make no sense.

"While the wording differs, in both cases the underlying criterion is the missile’s tested capability".

If the negotiators had wanted the same criterion for GLBMs and GLCMs, they could have easily written it that way.

On the 9M729 Controversy Under INF Treaty Rules
A followup to my reply bsky.app/profile/kady... to the discussion on 9M729 (re)initiated by @frhoffmann.bsky.social
Under the INF Treaty, “range capability” is defined for ballistic missiles as “the maximum range to which it has been tested,”

The article overlooks a key point: the risk of instability stems from Russia’s use of strategic nuclear weapons systems for conventional attacks. It is unrealistic to use strategic assets and expect them not to become legitimate targets.
