I think it was just a structural upgrade/maintenance to increase the lifetime of the airframe. I don't think the aircraft are upgraded in terms of capabilities. Thus, they stay as Block 30.
The US is coming for China. Pompeo is already preparing allied nations. The US, UK and Australia have made harsh remarks on China lately. China needs to answer for decades of rogue behaviour at the international scene.
Russia only suggests cooperation in space when they realise they can't do it alone.
Russia is history in space. They do not have anything to offer anymore.
Personally, I do not think anything will happen on the Aegean front in the next 2 years. Turkey needs time to produce plenty of SOM, ATMACA, Gezgin and Hisar O to make the conflict easily winnable.
Also, Syria and Libya need to be settled to free up resources.
Turkey has understood that the status of the islands in the Aegean is unacceptable. The matter needs to be settled. However, Turkey needs Greece to make a stupid move which will legitimise Turkey's action. I think the Navtex, Hagia Sophia etc. are all part of making Greece do something stupid...
Agree - If Turkey had joined the EU it would grant the Turks somewhat similar influence on Europe as during the Ottomans. The EU could never allow that to happen, as such, Turkey's persistency to join the EU was a waste of time.
Brother, I have observed that you have lately shifted into very conspiracy-like-thinking. Is everything alright? Maybe a small break from geopolitics would help?
Absolutely, with this many enemies, hostile and rogue states around Turkey nuclear weapons becomes a must. Turkey needs to secure its survival by having nukes and a striking capability which covers the entirety of earth.
