As someone with 'Migrationshintergrund', I have more than an average interest in preventing xenophobia from settling in the mainstream. Aside from the measures needed to integrate the refugees already here,

• Massively hike contributions to UNHCR because they are severely underfunded. It's so much more effective and less life-threatening.
• Likewise massive support for the Italian, Greek, and Turkish governments. Something that should have been done years ago but now is a good time as ever to throw them some money.
• Make a decision in the Syrian war. If Assad needs to be helped to victory to stop IS so be it. Or find some other way.
• This is minor: later on, Merkel will have to come out and just say that people shouldn't pay thousands and risk their lifes to make the trek. I know desperate people will ignore that and I know that it won't go well with her current image as a benevolent mother and our image as the current 'world champion of humanitarian relief' but you can't leave out the signaling. There are push factors and there are pull factors. Between those are the cold sea and barbed wire.
• And for heaven's sake pass an immigration law. They should have done it in the early nineties but "we are not an immigration country!" was the tenor in the CDU. Maybe they have learned a bit by now.
