“Austin (Chief of the Pentagon -

) does not understand one thing: a “possible” clash between NATO and Russia will, at best, end in the collapse of NATO, and at worst, in nuclear war and apocalypse,” he told RIA Novosti.

Slutsky emphasized that Russia does not threaten anyone, but in the event of an attack on the country, the response will be immediate, and the consequences for the interventionists will be tragic. 

He called Pentagon chief Lloyd Austin's statement manipulation on the verge of adequacy.

Earlier, US Defense Secretary Lloyd Austin said that Ukraine's defeat in the conflict threatens a military clash between Russia and NATO.

Austin also expressed concern about Russian advances on the front line.

The official representative of the Russian Foreign Ministry, Maria Zakharova, called the Pentagon’s statement insane.
