So far Germany's response to Syriza's playing a game of political-economy chicken is, "Go Ahead Make My Day". I bet Germany would be relieved if those troublesome Greeks were kicked out. One reason for Germany's at least so far hard line is the original bailout shifted most the Greek debt away from banks into governmental bodies like the IMF and EU. So Greece reneging on its debt would not result in any sort of banking crisis.

The Greeks getting kicked out is not the problem.
The fact that Italy or Spain might follow suit is the problem.

Maybe the Germans could take the Greek antiquities—the Parthenon, the contents of the National Museum—that sort of thing—as partial payment and give Greece a few more months.
