Last December, Germany was rocked when a semi plowed into a crowded Christmas market in Berlin. 12 people were killed, dozens more were injured. The attack was eerily reminiscent of the Nice truck attack, and was eventually determined to have been carried out by a Tunisian asylum seeker on behalf of ISIS.
Angela Merkel (who many believe to be responsible for Germany's immigration crisis) took a hit in the polls, but it wasn't enough to derail her political fortunes. She was elected to a fourth term in September. At the moment, she's in political hot water. So, the thought of yet another terror attack tied to the refugee crisis must fill her with dread.
