Incoherence

 Putin's sputtering, rage-filled speech and actions are incoherent, in the sense that they don't hold together.

He is trying to threaten the West with vague statements of nuclear threats and blowing up pipelines, so that the West will force Ukraine to the negotiating table. 

Meanwhile, the illegal annexation of Ukrainian oblasts makes negotiating impossible.

As his military faces collapse, he needs a negotiated settlement. But his annexation makes a negotiated settlement impossible. 

Madness.
