same thing applies to S-400s, right now you can't use S-400s against your biggest problems in Syria, that is just the reality of relying on foreign countries for weapons.
Lets be honest here, Greece or France are not really issues to Turkey, Egypt may be a rising issue, but US will definitely back a NATO country against Egypt, US even blocked sales of French cruise missiles to Egypt.
I remind you again , Turkiye wants to buy PATRIOT from the US since 2013 but the US did not sell PATRIOT to Turkiye
even Turkiye cancelled buying HQ-9 Air Defense System from China , still the US did not sell PATRIOT to Turkiye
therefore Turkiye bought S400 from Russia because of Turkiye has no any Air Defense System
even poor Greece has PATRIOT and S300
and our biggest problems in Syria were with the US who used Pkk/Ypg terrorists to create terror corridor in N.Syria against Turkiye
Russia has no power to force Turkish Army to leave Idlib and Syria
over 3400 Turkish Tanks,Howitzers,MLRS,AFVs,IFVs enetered Idlib in the last 20 days
Turkish Army-Airforce can burn not only Idlib but also whole Syria
problem is there are very strategic projects with Russia like AKKUYU Nuclear Power Plant , TURKSTREAM gas pipeline , S400 ......... but if Russia start a war with Turkiye , then nobody will care about strategic projects and Turkish Armed Forces will fight Russia in Syria because of we never allow bandit countries to create Pkk/Ypg terror state in Syria for destroying Turkiye's territorial integrity
Greece and France wants to steal oil-gas reserves from the Turks in the Eastern Mediterranean
and now French Aircraft Carrier - Frigates are in S.Cyprus against Turkiye
Greece are waiting for France to attack Turkiye
the US-Israel-S.Arabia supported SISI to make military coup for destroying good relationship between Turkiye and Egypt
now they use SISI's Egypt as a pawn against Turkiye in the Eastern Mediterranean and Libya
