Keeping who out? OF COURSE people from the Middle East will take an open door to Germany...just as they would to US, or Canada. Doesn’t mean shit. All it means is that they are a WELFARE STATE, couple with a ripe takeover target.
ANY Western country that opens its borders will get FLOODED by the Third World, nothing special about Germany.
Open borders? Germany has an open door with other EU members (with restriction against receiving welfare), not to the third world. Unlike President Trump, who wants to make 1.8 million illegal “Dreamers” American citizens... the war refugees are not citizens and can legally be shipped back to their country once it is stable whether they like it or not. Which has begun already with refugees from Afghanistan.
War refugees I might add, that were created by US incompetence in the Middle East (Iraq, Afghanistan, Syria). I am sure Germany would say you are welcome if ever a thankless slob would thank them for their humanity.
