I documented the Taliban extensively. Particularly in 2010, I was with Canada and the U.S. forces. In 2012, 2014 and 2016, I was supported by four other countries, primarily Germany. I was all over Afghanistan.
The Taliban were and still are, in my opinion, in lockstep with ISIS-K. ISIS-K is just an extension of the Taliban. NATO forces and the intelligence services, Canadian included, for whatever reason chose to ignore how serious the Taliban resurgence was.
In 2016, ironically, I went in with Russian forces into Kunduz. They were able to push back, with NATO forces, the Taliban resurgence in 2016. It took all of less than a week to do that. I was with six different countries on that mission.
However, after that moment, they should have realized that the Taliban were gaining regular footholds, and it was ignored. I don't understand why the intelligence communities, worldwide and NATO-wide, ignored journalists who were on the ground and warning about this issue.
