Symkaria
From Transformers Wiki
Symkaria is an eastern European country. They live next to Doctor Doom, which kinda sucks. Silver Sable is apparently a member of their armed forces.
Fiction
2005 IDW continuity
Symkaria was being bombed by Decepticon jets. They were also under the influence of the Decepticons' hostility-inducing machine. They blamed the bombing on the neighboring country of Latveria and gave them a 24-hour deadline before they counter-attacked. Silver Sable and the Symkarian army were on stand-by and were monitored by both S.H.I.E.L.D. and the Autobots. S.H.I.E.L.D. was especially concerned about the situation since Symkaria recently developed nuclear weapons. The Avengers were sent to investigate. Man and Machine, Part One
Both the shelling and the influence of the Psycho-Prism eventually stopped (thanks to the Avengers and the Autobots) and Symkaria retracted their threat of attack. Man and Machine, Part Four
