It is not insane, given the goals of Merkel.
You are looking at it from a different viewpoint than she is.
Put it this way, if you have a cancerous tumor, you surgically remove it. You do not put a bandage on it, ignore it, and hope it will go away. All that does is allow the cancer to metastasize and grow until it kills the host. Germany is in the same position as the patient with a cancerous turmor...get rid of it!
