Turkmenistan, Uzbekistan, Kyrgyzstan, Tajikistan and Kazakhstan, these 5 states were one state before Soviet Rule : Turkestan. Soviet rule did their best to encourage diffrences and to destroy similarities. But they still have a lot in common. Also Turkey and Azerbaijan is very very close in culture, in language etc.. I had been in Kazakhstan, Turkmenistan and Azerbaijan, Kazakh language is more distant to others and infleunced from russian too much but their culture , dishes very similar to Turkish. Turkmenistan is a bit more similar like its name

Azerbaijan has no diffrence than any anatolian region. So, Something like Turkic commonwealth would be a wise idea. There is no doubt that we have much more in common than Germans and Frenchs but they formed an union.
But I am sure neither Russia nor China wouldn't like such idea, maybe US and EU also wouldn't want such emerging power. Russia could even take the risk of war. Because it could cause an action in all Turkic lands, inside Russian Federation territories, there are a lot of Turkic autonomous regions like Tatarstan, Baskurdistan, Altai, Tuva, Qaraqalpak, Yakutsk.
Even north of Afghanistan is Turkic, thats why there is no problem in north

Gen. Rashid Dostum with his 25k troops from north aligned with NATO because Turkey said so.
Also, Xinjiang of China is populated by Turkic Uighurs and region called as
Eastern Turkestan.
Also %38 of Iran's population is turkic (mostly
Azeri and others)
So, a turkic awaiking, a turkic brotherhood is a danger for many major states.
Meanwhile there are serious developments for relations like Baku-Ceyhan Oil Pipeline. Now a second pipeline for natural gas, a trans-caspian pass for Turkmen natural gas and Kazakh oil are under construction, There are projects like Highspeed Railway from Istanbul till Baku and maybe a trans-caspian pass to central asia as well as highway roads. (China offered support for these modern silk roads) Main problem, Leaders of these countries still have deep ties with Russia, most of them ex. communist party regional leaders. To achive this Turkey tried some covered operations like assassination attempts, coups but all failed, and these caused to freeze relation for 10 years.
As I mentioned this states are rich in natural resources, kazakhs even have Baikonur space center, Turkey have military and man power, Azeri Turks are good at science. Thanks to russians this states have good infrastructure maybe better than Turkey (at list cities)
I am supporting a peacefull turkic commonwealth, but there are also some dangerious groups in Turkey supporting the samething for some racist or imperial ideals, they should be kept away of this.
