Recently, I asked whether the Greek government actually wants to strike a deal on its debt, or if its increasingly erratic approach to negotiations might reflect a determination to ensure that Greeks blame their creditors, not their government, for a coming meltdown.

The answer to that looks more affirmative by the day. But is Syriza's tactic working? And is the Greek argument justified?

A Greek delegation traveled to Brussels over the weekend, ostensibly to make a last-minute effort to bridge the widening differences with European creditors. Such meetings usually take all night in Europe — if they're serious. This one lasted about 45 minutes before both sides agreed there was no point to the meeting.
