I think Putin is quite confused about what is terrorism. Ruzzia is at war in Ukraine and it is perfectly legit to hit military targets. An strategic bomber perfectly qualifies as a military target since it is a plane intended to drop bombs and missiles to an adversary

Kiev is right that they have been able to hit targets at a long range. The fact that the delivery vehicle apparently was a truck (or a lorry if you live in the UK) does not change the fact that they have effectively being able to hit targets as far as Siberia. As far as strike capabilities, it could have been carried out by using a turtle to hit the bombers - this is war and you do not get points for having a pointy missile instead of a truck as a delivery method.
Ruzzia has been caught completely. It has been said that even the drivers of the trucks were completely unaware of the presence of the military drones that were hidden under a false floor. There are videos of people actually trying to take down the drones with stones.
This operation is going to the history books as the biggest aviation catastrophe for Ruzzia's aviation, done by a country with a force 20 times smaller.
