But with stating that Russia does not want a attack capability I simply must protest. S-300 and S-400 systems are defensive, but they have enough range to shoot down planes across the border. An S-300 in Damascus can shoot down a plane over Tel Aviv.
A car can be used to murder someone... that does not imply that all car designers and manufacturers intend cars to be used as murder weapons.
S-300 and S-400 were designed for the purpose of removing enemy air assets from the skies.
The fact that they can bring down aircraft 400km from the the launchers does not mean they are intended as a substitute for strike aircraft and bombers or cruise missiles for the invasion of an enemy state.
they are merely evolutions of previous generation systems with incrementally higher range performance.
Between two superpowers, there is no aggressor or defender, there is the victor.
Between Russia and the USA/West there is clearly an aggressor and a defender that reacts to the aggression... the amusing part is that if you listen to what they actually say it would be the aggressor claiming to be the defender...
