the statement of shaikh ibn uthaymeen is good enough for me. Very logical. If me joining teh ranks of teh kuffar, hinder islam (such as being posted in a muslim country and aiding teh slaughter of musilms) then its kufr al akbar, if me joining aids islam (example if you learn some technology and you have a realistic chance of then working ina muslim country and developing those same tactics or technologies there) then its permissable and even recommended.

Makes sense

remember the issue of realism is important though. if you learn their tactics, will you have any opprtunity to teach it to teh muslims? If you work on some weaponry or aircraft technology or something, will you be able to work in the muslim lands developing this technology? In some cases the answer is yet, in some cases no. The key question is whether it is empowering the muslim countries or weakening them. Wallahu a'lam
