Drinking themselves (and us) into oblivion

The political elite of Europe are behaving like immature youngsters at a late night party.  They are drunk and know they will have a hangover in the morning.  The only question is do they stop drinking now and have a moderate to bad hangover or do they carry on drinking?  If they carry on drinking the onset of the hangover will be delayed but when it comes it will be so much worse.

The euro party is over so why are they still drinking? 
Best Wishes
