He has visited the 2017 G20 Hamburg summit which he described as a " dystopian nightmare " , claiming that " the real problem is the dogmatic slumber of the leaders of the free world , represented at this G20 summit by Merkel , May and others , which is the origin of our current dystopian nightmare ( wars , terrorism , the refugee crisis and climate change ) " . Since 2016 , he has been claiming that " the need for a progressive international movement was never as urgent as today " .
