No, this is not true. I think it is very unfortunate that the Jews, who were already suffering so much (and very unfairly) under Hitler in Nazi Germany, suffered even more after the declaration of war by UK and France, in September 1939, apparently brought the Holocaust, as Hitler had warned in January 1939:

(and, by the way, thank you to Saggy for his post).
I do think, however (we should always think a little about our current time, about 2020), that there is an analogy between U.S. and Israeli policies in Palestine, Iraq, Afghanistan (and towards Iran) and other countries on the one hand, and Nazi expansionist policies in Eastern Europe on the other hand.
Ah poor Hitler!! (Snark) The horrible allies forced him to persecute the Jews and mass murder them!! (Snark) No doubt they held a gun to his head and forced him to do it!!! (Snark)
What absolute rot. Hitler wasn't forced etc., to do it. He did of his own free will. What sort of ideological fanatic mass murders millions of men, women and children, by means of starvation, bullets and gas because he has a delusional belief that some how they are guilty of causing a war? Well Hitler was that sort of fanatic and just how safe were other Europeans and the Germans themselves with that sort of ideological fanatic prey to delusionary notions running around wielding power?
Already in January 1939 Hitler was planning for war with Poland and was concerned that like with Munich someone might deprive him of the war he wanted. So Hitler decided, well ahead of time, to blame others for causing the war he was planning to start. It is called projection. (I will here put in here that Hitler had started his preparations for war right from early 1933 on.)
Hitler hated Jews with an intensity that was truly remarkable and in my opinion psychotic. All you have to do is read Mein Kampf were you can find purple prose passages about Jews being Vampires, Jewish youths waiting to rape Aryan women, Jews being parasites etc. And of course you will find passages in which Hitler hallucinates that the Jews will destroy humanity etc. And a couple of passages where Hitler hallucinates with satisfaction mass murdering Jews via gassing! That such a man ruled a powerful nation is astounding. To me it is obvious that at least as early has the writing of Mein Kampf Hitler had decided that if he could he would commit genocide against the Jews.
To repeat All Hitler had to do to avoid war was not invade Poland. He did anyway knowing full well the risk he was running and then proceeded to institute policies that made peace, except at the price of destroying the Nazi regime impossible. (His liquidation of the Polish state etc.)
Before Hitler committed suicide he dictated a last will, where once again he whined about how "International Jewry" etc., forced him into war and that the real enemy paid for it with their lives, although Hitler then whined about it being by more "humane methods", and Hitler then proceeded to call upon the Germans to continue the fight Against "Jewry" to the end. UGH!! If there is a hell Hitler belongs in it.
Hitler viewed Jews has basically not just "sub-humans" but has anti-humans, whose existence was a threat to the survival of the human race. That along with Jews being compared to germs, parasites, disease in general was obviously genocidal in implication. Hitler's attempts to offload his responsibility onto his victims is mere projection. Just like his attempt to blame the war he wanted on his victims also.
That this murderous loon attained high office and wielded great power is one of the greatest, if not greatest, tragedy in human history.
