Korea has a significantly higher per capita GDP and Turkey is in a full blown currency crisis. In terms of societal capacity the two economies aren't comparable.
Iran is an economic basketcase. You think they have no capacity for research and development? Israel doesn't agree.
Ofcourse should global security ever deteriorate the EU can potentially field an army as large and advanced as any in the world. The cold war was not won by the US alone. But every cent spent on missiles can't go to healthcare or education.
