Russia has introduced hi-tech pieces of military equipment and strategy during the war in Syria.
Vladimir Putin’s intervention in Syria has been a game changer and what happens there now lies, to a large extent, in his hands.
Russian military jets have, at times, been carrying out more sorties in a day in Syria than the US-led coalition has done in a month.
The Russian navy has launched ballistic missiles from the Caspian Sea 900 miles way, and kept supply lines going to Syria.
The air defences installed by the Russians in Syria and eastern Ukraine would make it extremely hazardous for the West to carry out strikes against the Assad regime or Ukrainian separatists.
The chief of US Air Force operations in Europe and Africa, Lieutenant General Frank Gorenc, has disclosed that Moscow is now deploying anti-aircraft systems in Crimea and Kaliningrad.
It is not just Nato member states watching the Russians with concern. Israel, too, sees the build-up of Russian weaponry across its northern border in Syria and wonders where it will all end.
Mr Putin has relished pointing out the significance of the West seeing “for the first time that these weapons do exist, that they are of high quality, and that we have well-trained people who can put them to effective use. They have now seen, too, that Russia is ready to use them if this is in the interest of our country and our people.”
