You ignore that most western platforms are linked. Any weapon system will use a whole bunch of suppliers from across the differant NATO countries. Leo, Leclerc, Challanger, Ariete I believe all share the same German 120mm Rhienmetall gun. Ditto for choppers, planes, subs etc etc. There is a basket of suppliers and each country purchases from them to build their 'local' iteration. The analogy of VW might not be exact but I think still it helps. VW platforms are sold as Seat in Spain, Skoda in Czechia, with even Audi sharing some technology. Of course the US leads in the spectrum and depth.
You need to talk to Bosniaks or Kosovars - there is some in UK to see what you say holds any currency with them.
