Ejection is not possible by the constitution.unlike the Amhara, Greece actually had a psoitive disposion towards th european constitution. They just had difficulty following through with their fianacial obligations that caused the revocation of their votting rights!
Amhara however hate everything about the Union that the rest of the region either like or have learnt to live with it! Why then do we keep tolerating one region whose compliants never end, hating everything that doesnt come out of amhara? They wont change either unless we resolve to find an exit plan for them!
