On the refugee crisis, quoted on Ekathimerini, FYROM ‘paying for EU mistakes' in refugee crisis, says Ivanov http://www.ekathimerini.com/206888/article/ekathimerini/news/fyrom-paying-for-eu-mistakes-in-refugee-crisis-says-ivanov, March 11, 2016.
Context: In the refugee crisis there is the humanitarian aspect and the security aspect. In terms of humanity, Germany acted very well. But in terms of security, your country has completely failed. But no one has the courage to say what still lies ahead. Between Sudan and Egypt alone, 20 million migrants are waiting to come to Europe. The refugee flow won't end, because everyone knows everything via Twitter and Facebook.
