At the moment I'm celebrating as well as being wary. Just because they are the Taliban, we shouldn't give them a free pass. In fact they should be held to a stricter standard. It's very early days so let's wait and see how things pan out.
I don't know what their justification is in forming a relationship with China, but I'm hoping and praying that it is all in Allah's plan and inshallah we shall see the benefit. My mind keeps thinking back to the treaty of hudaibiya and how it ultimately lead to our benefit.
The first time Taliban took over, they allowed the losing side to join Taliban and gave them the same positions they held when they were in opposition to the Taliban. They also allowed the opposition to hold official positions in some areas such as Kabul. I can understand their hikmat behind this, but it backfired. The ex opposition holding positions in the Taliban gained numbers and strength and caused problems for the main leadership, including ameerul mumineen mullah umar (rh). I hope this doesn't happen again.
I think this is a very critical time and the Taliban need help and support from our scholars, world leaders, and general awaam.
