Germany accepted, with much fanfare, a large number of unregistered refugees from Hungary and offered them a warm welcome. This decision arguably tempted so many more refugees from the Arab countries that soon thereafter Germany was forced to impose border controls.
根据《都柏林公约》（Dublin Regulation），移民所抵达的第一个欧盟国家有义务注册并处理移民的申请。这一规定早已名存实亡。希腊和意大利对移民无动于衷。德国接受了大量来自匈牙利的未注册难民，并给予热忱的欢迎。大概是这一决定诱使更多来自阿拉伯国家的难民涌入而德国，很快就导致德国被迫开始边境管制。
