In an interview with the German magazine Der Spiegel, leader of the New Flemish Alliance (N-VA) and mayor of Antwerp Bart De Wever stressed that the integration of Muslims in his country has been unsuccessful.
"We failed to offer them a Flemish version of the American dream," De Wever told the magazine. "That is our problem," he added.
In the interview, which took place before the attacks in Brussels, De Wever criticized the inefficient state apparatus of Belgium, viewing it as "slow, complicated and inefficient," and opposed the current policy of German Chancellor Angela Merkel.
Merkel has been lately criticized over her refugee policy, which has drawn anger from within her own party, Germany as a whole and within the European Union. The growing influx of migrants started to raise anxiety and concerns among the local population.
In 2015 alone, over 1.1 million refugees entered Germany and their number continues to grow. All in all, the EU border agency Frontex recorded more than 1.8 million illegal border crossings into the bloc in 2015.
