Poland waiting has little to do with politics and more to do with when contracts were signed. They only signed in 2020.
Turkey is trying to develop their own 5th generation fighter after getting kicked out of the f35 program due to being a leaky sieve sending data to the Russians. That’s on them.
By and large, the wait elsewhere is mostly to do with the bad reputation the program got before it was operational. Now that it’s all in the past and it’s proving to be an excellent fighter, contracts with allies are coming in faster than they can be produced. That’s the price of waiting.
