Armenia's prime minister said the CSTO, seen as Putin's NATO, "creates threats" for his country's future existence, after it pulled away from it.

Russian President Vladimir Putin has warned NATO alliance leaders that a move to lift restrictions on Ukraine’s use of longer-range Western missiles to strike deep inside his country would be considered an act of war.

Earlier this year, the Daily Mail predicted that a Russian conflict with Nato would begin with "massive cyberattacks" and "missile strikes" on targets in Eastern Europe and beyond. Russia would later embark on a land, sea and air invasion of Lithuania, Estonia or Poland.
