I thought this was an interesting piece in der Spiegel.
Merkel apparently sought to take the wind out of Erdogan’s sails by hastily having her spokesperson announce that the Böhmermann poem was “consciously injurious.” She could have thrown her support unmistakably behind Böhmermann, as one might expect from a chancellor charged with defending the German constitution. His poem was very clearly meant as satire; none of the uncomely imputations therein should be taken – nor were they meant – seriously. The chancellor, of course, knows as much. Yet by adopting Erdogan’s viewpoint, she has essentially allowed him to determine what should be viewed as satire in Germany and what not. Now, the chancellor must decide if German prosecutors should be allowed to open a case over the insulting of a foreign head of state – but because she already described the poem as “injurious” via her spokesman, she has very little room for maneuver.
Erdogan, like the trolley that he most certainly is, isn’t satisfied. Rather than wait for Merkel’s decision, he went ahead and filed a criminal complaint against Böhmermann himself. That case will move ahead no matter what Merkel decides.
