In Cheneyworld, that would be an act of war. So why aren't the Cheneys attacking the German government for its "mindset" problem? Because they have no political interest in weakening that administration, and they do in attacking the American administration. Or they're more scared of Angela Merkel than they are of Barack Obama.
Unlike the US, Germany has had a recent successful experience in rolling up a terrorist threat against the country, when the Baader-Meinhof Gang was dealt with as... a criminal conspiracy. If this were a country where other countries' successes at least suggested something to be emulated, that record might be persuasive. But despite our self-image as a nation obsessed with success, some of us, at least, seem more obsessed with making a political point than with pursuing a successful course in dealing with terrorism.
