Turkey has NEVER developed a single fighter aircraft, if I am not wrong. British Tornados are in service in multiple countries at the moment, not to mention EF (Britain can build national fighter aircraft on its own too, it's much less costly to share the burden with its coreligionists and Western European NATO members and neighbours).
Japan can also build multiple fighter aircrafts as it has past experience in this field, and also it developed the Mitsubishi F-1 in the recent past.
In simple words, Japan and Britain both have greater experience, more money, more researchers, more industrial output, and therefore, greater capability to design and mass-produce their own state-of-the-art fighter aircrafts if they are embargoed by the whole world. Turkey is zero in front of Japan and Britain.
Here's some introductory materials for inattentive youngsters to read.

Any member who just glances at the two links above can realize the immense gap between Japanese/British aerospace industry and Turkish industry. Except some teenagers with pimples ranting on these silly fora, nobody on earth would even dare to speak such utter nonsense as "Turkey is stronger than Japan/Britain militarily".
Not there YET! While Britain and Japan has dozens of indigenous engines for every type of vehicle they use, and they have had them for decades.
Not there YET! While Britain and Japan has had those capabilities for decades. Everybody knows about British missile capability, don't forget that Japan has launched probes to moon, other planets, launched its own satellites etc.
NOT like Britain. Britain developed and tested its OWN nukes. It was the third country in the whole world to test its own nuclear device. Japan has had the capability, and can produce nukes in less than months, but because of its painful memory from Hiroshima and Nagasaki does not pursue that path.
Turkey has NO nuclear weapons production capability.
Turkey is the same as Belgium/Netherlands. Just store NATO's nukes at NATO bases on your territory because your country is weak enough, you need NATO "protection".
Not surprised. "Satellite Launch Vehicle".
No aircraft carrier.
No LPD/LHD yet.
Nuclear powered submarines are only possessed and operated by strongest countries in the world. Thank you for agreeing with me. Turkey does not belong there.
No destroyers in Turkish navy. Japanese Maritime Self Defense Force operates heavy destroyers, frigates, LHDs, and actually built tens of aircraft carriers (you know those "ships" that carry squadrons of aircrafts for "power projection") in the past. British naval history is not much different in this regard.
Nobody thinks Australia, with a larger economy than Turkey, is a world military power stronger than Britain and Japan. Turkey with its small economy compared to Japan, Britain and Australia can not be considered stronger than Britain or Japan.
Silly rant. This "brotherhood" does not allow you to sign mutual defense treaty with Iran and Pakistan. You are still a member of NATO. When you leave NATO, and join Iran, Pakistan in mutual defense treaty obligations, then your silly rant may have some validity.
