Spain's economy is headed for a depression, Ireland's credit is shot after their bailout, Portugal collapsed almost immediately and is suffering high unemployment even after a bailout, Cyprus's credit rating is junk and they've applied for a bailout. So it's not just Greece. Several other countries were headed for trouble but seem to have things under control now: Italy, Belgium, France, the UK, Switzerland, Germany, and Slovenia.
Even if I were to agree with you on the collapse, that’s not all Euro countries. Germany, for example, had never any problems or trouble that could by any sane person be described as collapse.
