Escalation most troubling. Armenia and Azerbaijan. The conflict worsens? 

"Watch: Armenia's S-300 Missiles [Grumble] Active Over Yerevan As Azerbaijan Steps Up 'Suicide Drone' Use"

DEVOTED READERS TO THE BLOG I RECOMMEND THE EMBEDDED VIDEOS.

"The war between Armenia and Azerbaijan over the disputed Nagorno-Karabakh border region appears to be spinning out into a broader conflict as footage of increasingly heavy and advanced military hardware is appearing. As of late Thursday there are reports that Armenia's Russia-supplied S-300 systems are active near the capital of Yerevan. New viral video circulating on military channels purports to show S-300 missiles intercepting a possible enemy drone or inbound rocket in the vicinity of Yerevan."

Additionally:

You Tube video in the Turkish language only. To give you some sense of the size of the Harop "suicide drone" so-called. Primarily [?] an ISR drone [intelligence/surveillance/reconnaissance] but also having an on-call kinetic-kill mission.

In some quarters the Zero Hedge Internet web site described as: "Zero Hedge or ZeroHedge is a far-right libertarian financial blog, presenting staff-written articles and aggregating news and opinions from external sources."

Devoted readers to the blog take it from there. It is your decision. Zero Hedge or no Zero hedge.
