It seems that because of the Taliban, all the neighboring countries of Afghanistan will be in a fever due to the possibility of military and terrorist actions in this region. After the Taliban seized power in Afghanistan, the activities of various radical Islamist groups will intensify and the hotbed of tension in this region will inevitably grow. In response, the United States and other states will also take appropriate military measures and it is difficult to even imagine what this might lead to. A significant part of the active members of the Taliban consists of Uzbeks and other nationalities of Central Asia, and this military center can be transferred there as well. If this happens, then Russia will also be involved.
Therefore, difficulties will soon arise not only for Pakistan.
Uzbeks comprise around 8%-10% of the population of Afghanistan, and therefore you can naturally expect a few of them in the Taliban rank and file. But Taliban is dominated by various Pashtun tribes, with a large portion coming from the Kochi nomads. Dari (Afghan Persian) speaking groups are rare in Taliban, so are the ethnic minorities such as Uzbeks, Hazaras, Pashayis, Nuristanis and Pamiris. And countries such as Tajikistan and Uzbekistan are already concerned about the warfare spilling over to their territory. Tajikistan has already started providing arms and ammunition to the Northern Alliance (which is mostly comprised of Dari speaking Tajiks).
