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.
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.
