You can't provide any logical or rational argument to support the view of "that West did not really differentiate between those groupings or even admit that some of the more prominent groupings were radicalized", simply because there is no evidence for such a viewpoint.
Again: Such view is simply wrong.
Sure I can, but should I really provide evidence of western support behind Afghanistani anti Soviet combatants?
"West-Policy", "Western interests"...
You should really start thinking about your problems with anything European or American.
So you deny that Western parties protect their National (and allied) interests? Or did I misinterpret? I would be glad if this (possible) misunderstanding could be cleared up, if you so wish I will try to explain my position into greater depth on any specific topic related to this discussion.
