While Putin...

Responded to Biden's invective with humor and class, features neither Biden nor ABC have:

What was truly important is Shoigu's "admission" that:

"Не буду скрывать, что и сегодня в Сирии на оперативном, на тактическом уровне у нас очень тесные контакты с американскими коллегами. Может быть, если это для кого-то секрет, я его открываю, этот секрет. У нас на уровне наших, по гражданскому назову, управленцев в воздушном пространстве и ведению работы в воздухе по борьбе с терроризмом по несколько раз в день бывают контакты"

Translation: I am not going to hide the fact that today in Syria, both on tactical and operational levels, we have very close contacts with our American colleagues. If this is a secret for someone, well--I divulge this secret. We have, using the civilian lingo, on the level of our managers several contacts a day regarding operations in the air while fighting against terrorism.    

This statement by Shoigu is not accidental and is "loaded" with meaning and underscores what I talk about all the time--the last vestiges of the American competence on a governmental level are primarily with the US military. Even if for the reasons of the American military professionals being capable of a solid risk assessment, people in State Department are not capable of. In this case US-Russian military channels of communications remain THE ONLY reliable means of communications considering an appalling lack of professionalism in the US foreign policy establishment, and, frankly its inadequate mental state.
