I think that Caucasus is not an European area of influence but it is properly Europe if you consider ethnolinguistic and religious elements. A Great Europe could also be an equilibrium in Russia-Caucasus (especially with Georgia) relationship. A Great Europe should be seen as a shield for the little nations against the bigger state's imperialism.
Concerning the problem of non European immigration, a Great Europe is also a solution by promoting easy immigration and facilities for European citizens and restricting non European immigration. Many young Romanians or Bulgarians come for working here at West. As a consequence, Romanians or BG employers must hire non European immigrates. A Great Europe should permit to Western Europeans to settle easily at East (and the same at West for Eastern Europeans). The problem here concerns the salary. A Great Europe should grant a minimal socio-economical standard for all the citizens (with a focus on salaries increase).
