Australian govt funded broadcaster article on the intercepted phone conversation between German officers. The facts are;
A phone conversation was released, confirmed, verified as accurate and true.
German high command were discussing specifics on an attack on Russian infrastructure, how it was impossible for Ukraine without their direct assistance. They talk of war with Russia without the governments knowledge, approval or direction. (the German government anyway). British and French forces exposed as operating in Ukraine. Russia responds; "If nothing is done, and the German people do not stop this, then there will be dire consequences first and foremost for Germany itself," Russian Foreign Ministry spokesperson Maria Zakharova said." Not a threat, a confirmation there will be consequences if Germany attacks Russia in this way. Serious stuff.
But look at the language in the article.

"Russia is threatening Germany over a leaked call". (In the phone call, Germany threatens Russia.)
"This is absurdly infamous Russian propaganda,". (admitted to as true).
Luckily, German's do not want war and are reacting.
NATO.
