By means of explanation: Jarosław Kaczyński is Polish. He made his speech in Poland. Poland is a medium-sized country in Central Europe. The citizens of this country are called 'Poles'. Poland has a history of conflict with Germany. For example, Germany invaded Poland in 1939.Jarosław Kaczyński, leader of the Catholic nationalist PiS (Law and Justice) party, attempts to stir up old hatreds between Poles and Germans.
I think conflict is 'bad'. I believe it is a 'bad thing' for politicians to cause conflict.
I hope the above explains the context of the O.P.. I have also, as requested, expressed an opinion on the matter.
