I would give a few weeks for propaganda on both sides settle down. I read various conflicting stories from both sides. There are stories i read from quora that the talibans arent stopping people from getting to the airport, they even set up checkpoints to see who got pass and let them through, while the one stopping them was actually the US own forces holding the airport.
But they're just that, stories. Doesnt take much for reporters to claim an unidentified sources, post a pic and create all sort of narratives (from both sides). We probably dont see much from the taliban sides but a friend of mine read aljazeera in arabic and they paint a rather different optics says he.
One thing for sure it's 21st century. Any incidents can be captured live on smartphones. With satellites, and many expat still lives in Afghanista. We're bound to find out if there's mass killings or any other extreme brutalities from amateur video.
I dont think the taliban are nice and kind. I just think that they're not stupid and at this moment will exercise restraints at least for the time being. Whether they remain open and moderate going forward only time will tell. It's not in their best interest to shake things up for the time being. They have the country won. Their biggest worry should be going forward, they're already undisputed de facto sole power in Afghanistan
Regarding refugees, i understand why it's a big decision not to accept Afghanistan refugees as it's a permanent commitment with huge strain on economics and culture. How are they going to house them, assimilate them, finance them. It's not like you can give quota, once a nation declare they accept and give nationality to Afghanistan refugees the rest will follow and at one point they'll have to send them back, whatever the excuse given.
