Does anyone think that the fact that at least 4, if not 5 countries, at minimium, are going to have to be kicked out of the monetary part of this Union (i.e. the euro) before 2020 in order for said monetary part to survive, will have an impact on the expansion in the European Union itself?
From an economic common sense standpoint; yes. However, I think that the political will for a United Europe is too strong for little things like economic sense to stand in the way. That all changes, of course, if Greece defaults.
