The world is on the eve of significant changes. Note August 22nd. The flare will be fired there. The world financial system, especially dollarization, may experience significant shock waves in the coming period. Forget linear growth projections and world economic forecasts for the 2050-2070s. The road is full of pitfalls and obstacles, and very few of those supposedly promising countries will make it to the finish line as predicted.
You need those African countries that you consider unimportant, where you have an officer stage a coup every 10 years on a Sunday morning. Because without that country, you will not have fuel rods for your power plants, your industry will not have the advantage of raw materials, and you will not keep their gold reserves in your own vault. You need it, you have to ensure it through cooperation, even if it cannot happen in a system of exploitation. TR is not a fully developed economy. But if the goal is to reach that finish line, we have to see which way the world is evolving. Economy, energy and food security, national security in the context of military capabilities... You can look at it from many different perspectives, you can't get everything by only fighting.
Regarding the KAAN project, I am not against opening this project to Azerbaijan and Pakistan. In fact, I am in favor of 'absolutely and positively' including Indonesia and secondarily Malaysia in this project in some way, through significant ToT agreements if necessary. We can also add some emerging economies of south/east Asia and the Latin region. And as far as I can see, the KAAN program (I'm talking about the whole concept, not just the aircraft itself) is on its way to becoming a euro-asian funded project. A security bond is the most lasting way to build a bond of trust. Sometimes it will not be enough to fight for yourself, you must also be able to liberate your friend.
TLDR, issues need to be approached holistically. Turkiye's indigenization efforts in aerospace and creating whole brand new independent*(as much as it can) industry are not the only necessary need to be done. There are issues such as energy, food security, macroeconomic stability. And even reaching up to the 'balance of terror' (you know what I mean) under the heading of Defense. There are some ways to accelerate these steps in a coordinated way. Or you can try to tackle them one by one with your limited resources and capacity: and all alone, ignoring the fact that you are blocked at every turn by those with whom you are formally allied.
