Ankit,
most of what you say is sensible but can we please not say things like 'will mean destruction of Turkey'? WhatI does such a phrase mean? Does it mean 90 million Turks will suddenly give up?
At the moment Russia has only faced a fraction of Turkey's total air assets. There is no doubt that Russia has more assets than Turkey, but Russia also has far more enemies than Turkey who are steadily building up their forces in Poland, Ukraine, the Baltic states, Georgia etc. In addition it's certain that Israel may not want a democratic government in Syria, but equally it does not want a Shiite terrorist movement which has grown vastly more powerful because Israel did not become involved. In those circumstances can you see Israel passing on its own knowledge of measures to defeat Russia's airdefence systems?
And of course China may provide economic assistance to Russia but what does that mean? and will China be prepared to do that when it knows that this will result in severe future problems with GCC and other Muslims states now aligned with Turkey (18 at last count)?
On the term, may be you got it wrong.
Just think about it, what will worry the men in power more, a few thousand lives or losing their business?
The answer is later, I meant purely destruction of Turkish power supply, water and gas.... you see a starved population is more painful than a dead one.
On air assets , I purely mean Russia at present has enough to defend that small portion of area from Aleppo to Damascus and that's what Russia cares for in Syria and it has at present quite an extensive air defence network in place, no denying to that.
As for Turkish airforce, you see the Russians are not the only problem for them, they need a sizeable amount of air and land assets, in western areas too, apart from Greece , Russia has the capability to open up that front too.
As for other enemies of Russia, the biggest one is Ukraine. And the situation is not quite peaceful there as well, Russians are fighting there too, so I don't expect a big difference even if Ukraine ups its offensive.
Rest states like Poland, they are not risking anything without NATO approval, and because you said in the beginning that we are considering only Turkey supported by Saudi and coalition so I haven't counted NATO and its options.
As for Israel. The truth is amongst all this they are enjoying the middle east neighbours killing each other, and they will surely wish for more.
As for one person commenting that Turkey will attack Russian power stations and dams too, the question is about the capability.
As for Turks giving up, I haven't said so not do I expect it to happen.
