“This event in Jerusalem has been manipulated. The fact that President Duda will not be able to speak and refer to Vladimir Putin's words is absolutely regrettable. The fact that others will be able to speak and to present their version of events, in particular Putin, and the Polish president won’t, is absolutely unfair and deplorable,” said Moorhouse. "The Polish President's boycott of this event is in my opinion the right thing. It drew attention to the matter, newspapers around the world wrote about it. This is the best what can be done: to speak the truth consistently” emphasized Moorhouse. Roger Moorhouse is a British historian and writer specializing in the history of World War II.
