You should watch the interview first @amadek. Putin never said that Poland caused WWII. Neither he said that Poles persecuted Ukrainians. Everything he said has been documented in the archives, and is true. There, in the Russian archives it is written that Ukronazis has murdered Poles, and therefore Red Army liberated Poland, and helped them regain Baltic port Gdansk, formerly known as Danzing.
You really should listen carefully what Putin is talking about and thank USSR for the territories Poland gained after WWII. If you deny it, well, then wait for Germans to come and ask those territories back.
