No, it’s not related to that.

No. Why would I? The question makes no sense.

Those are mercenaries, not volunteers. Mercenaries will fight for money and for who pays most. They won’t be generally motivated by high ideals. That type of person, no matter which nationality, won’t fight for their country because it doesn’t pay. Within this context, your original comment is highly misleading IMO.

Can you please provide some reliable sources for those claims?
