Spain back on the agenda

So, having had a few weeks off from EU worry, the market now seems to be back in fear mode with Spain being at the top of the agenda.  The pattern seems to be to go from one country to another, things seem to be quite with Greece for the moment so look at who is next on the list.  This type of fear is probably better than worrying about all of the potential black spots of debt crisis as a whole, but there is the impression that nothing ever gets resolved and how can it be?  The problem of debt that has built up over the last 20-30 years is so big that there is no overnight solution to it and markets tend to like solutions that resolve crises quickly.
