So, if it is, as we have been lead to believe, all about the war stupid, why would terrorists target Germany for attack? They opposed the war in Iraq and they definitely haven't been supportive of Israel. Why attack them? Maybe because they're not under Islamic rule?
And boy did they receive a break, if the bombs had gone off, they would have had a London type bombing on their hands:
The bombs were found in the German cities of Dortmund and Koblenz on July 31 with German Criminal Police Office (BKA) chief Jörg Ziercke saying that were arranged to explode simultaneously at 2:30 p.m. Neither of the bombs was detonated.(Link via Little Green Footballs)

The BKA suggested that Germany was being targeted for attacks possibly by a terrorist organization operating in the country. If the explosive devices had been detonated, their size and construction would have created devastation and death on a scale reminiscent of the July 7, 2005 attacks on the London transport system, according to a report in the Süddeutsche Zeitung newspaper.
Both of the suitcases discovered on July 31 contained gas cylinders rigged up to an ignition mechanism and had been left in two regional trains which usually run at the height of the commuter rush hour. The suitcases were discovered by rail staff when the trains terminated at the two hub stations. The construction of the devices and the potential impact the explosions would have had suggests a sophisticated plot.
