Best case scenario: They bombed themselves

Azerbaijan hits Armenian missile system in Nagorno-Karabakh.  Azerbaijan’s Defense Ministry says it has destroyed an Armenian air defense missile system in Nagorno-Karabakh.  Nagorno-Karabakh is officially part of Azerbaijan, but since a separatist war ended in 1994 it has been under the control of forces that claim to be local ethnic Armenians but that Azerbaijan claims include regular Armenian military. Efforts to negotiate a settlement have failed, and frequent clashes have continued.  WTOP
