The issue is not the so called "spy software" in S400 It's that they feel betrayed Turkey would cooperate with their enemy, Russia.
Which is ironic since they support PKK offshoots.
I don't understand the mental gymnastics behind thinking "F35 was bait" at the same time as "F16 block 70 will strengthen our air force" Do I need to explain to you that both are made by the same country? I'm utterly confused.
Look guys I'm onboard the anti-American hate wagon. I'm all in. But explain to me why we can't activate the S400 systems and why are we asking for F16s now?
We did a naughty thing by buying S400, we got slapped and we're going back to America now.
Except I am not saying ''we should be glad they didnt sell us F-35s! We are independent now!'' while on the other hand saying ''I hope they give us F-16 Vipers!''
I wish they sold us F-35s, all I am saying is that they were never going to anyway. Turkish air force has been left vulnerable for a decade as it relied on F-35s. I wish the transition to TFX would be smooth but the political conjuncture was screaming this turbulance was bound to happen.
F-35 right now is a strategical asset. It is a model for future fighter jets and the only proper gen-5 stealth jet on the market. They did give a lame ass excuse by saying S-400s are incompatible as they can be a spyware and study the profile of F-35 on radar as stealth is its primary feature.
Well F-16 vipers arent stealthy so there is no need to worry about S-400 radar figuring it out.
USA accused Turkey of fueling Russian defense industry(as if for all these years they didnt advocate for ''free market economy'' in all those third world countries) so we gave them a proposal of receiving F-16 vipers that can enable us to maintain the gap with Greece and if USA doesnt sell we will have a nice rhetoric against them.
They definitely didnt feel betrayed. Lets analyze what happened in chronological order.
0- June-July 2015: Erdogan calls on World that they will not tolerate a new state in the North of Syria and one month later PKK makes the Ceylanpinar attack and hence the so called ''solution process'' with PKK ends.
1- November 2015 Russian jet is shot down.
2- June 2016 Erdogan expresses regret for the shoot down of the Russian jet.
3- July 2016 the coup attempt happens and Vladimir Putin calls Erdogan out of solidarity before any Nato members.
4- 21 July 2016 Erdogan says the F-16 pilot that shot the Russian plane was a gulenist.
5- August 2016 Erdogan goes to St.Petersburg and the BBC commented that the summit, at which Erdoğan thanked Putin for his swift support during the coup attempt, ″unnerved the West″.
6- December 2016 Russian ambassador Andrei Karlov is assassinated by a gulenist.
7- December 2016 two countries initiate Astana Peace talks for Syria.
8- May 2017 Russia lifts the sanctions on Turkey.
9- September 2017 Turkey makes the S-400 deal.
Now along with this list I know two countries fight proxy wars in Syria and Libya. Libyan issue is not hot as I suspect both sides despite supporting opposite sides enjoy the status quo but in Syria both countries interests clash. For Nagorno-Karabakh I am pretty sure both were happy with how it all turned out.
Now all these above are the data we have as ordinary citizens. When you look at the chronology one thing is pretty clear. USA tried to spoil the relationships of Turkey-Russia both with Karlov assassination and jet shootdown yet Turkey and Russia still approached each other.
Buying a new weapon system is a mark of reorienting in foreign policy. Turkey didnt buy S-400 all of a sudden. It was a long coming development and it happened.
