Alex and Alexander in Athens.
Alexander leaning toward accident explanation. No visuals of a missile strike. Air base is well protected so sabotage not very likely. If it was sabotage, then the Russias have to tighten up their security. Russians have hundreds of planes so the loss is not as catastrophic as it could be.
The military situation reminds Alexander of South Vietnam and Afghanistan; neither of these military operations were successful. There are similarities with Ukraine.
Russia continues to make advances in Donbass. The collective West knows but cannot / will not admit it. Keep throwing financial aid.
