Polish water cannon are being deployed because, here on the Belarusian side of the border, migrants started throwing rocks, bricks and branches towards the Polish forces.It’s a scene of chaos which is continuing. It feels very much like a pre-planned provocation. It seems as if a decision has been taken on this side of the border to try and exact a response from Poland, and from the EU.This image is very much what Alexander Lukashenko wants to transmit to the world. Belarus has been trying to portray Europe as uncaring and uncompassionate, inhuman even. And certainly Belarus will use this to portray that image of Europe to the world.
