You clearly don't know that the Final Solution was in fact a desperate measure during the last stages of the war.
You also clearly don't know that racial prejudice was in fact mostly internal propaganda and party-related ideology. That the actual war had nothing to do with it but instead was the product of an historical context in order to reclaim land lost to WWI and expand the territory and influence of the Nazi Germany. Germany would in fact recruit from many of the countries it occupied. Not exterminate them.
You also don't seem to know that the occupied countries, with exception to those holding pre-WWI German territory were meant to become after the war satellite states within the notion of a decentralized German Empire.
But more importantly, you fail to reveal any knowledge on USA's Neutrality Acts and Cashy & Carry policies. The first even deserved the following comment by Roosevelt "American neutrality laws may actually give passive aid to an aggressor while denying help to victimized nations." And the second being one of the major contributors for Japan attack and Germany & Italy joint declaration of war a few days later.
It would be only in 1941, exactly 2 years and one month after the war started that the Neutrality Acts were finally put to an end. But ironically even then USA non-intervention policy was meant to proceed while the world tumbled all over it and its allies kept losing the war (and USA ships kept being sunk by german U-Boats!). Japan however had different plans that revealed themselves one month later... and then USA was indeed forced into the war. But meanwhile the Neutrality acts favored the development of Germany, the beginning of the war and the success of the German-Italy early campaigns while emptying the allies coffers and instigating Japan.
So, from the bottom of my heart I thank your grandparents and their fathers and mothers who sacrificed their lives and the lives of their loved ones for a just war. But don't think that will hide your country faults neither it will wipe out from history the millions of others from many other countries, who them too sacrificed themselves. Neither for one moment think that your patriotic propaganda will make it look like this war would have never reached your shores (it did in a terrible way), or that somehow you acted out of pure goodwill and uninterested desire to help your allies that were being slaughtered in Europe. You didn't. You were sheepishly dragged to this war. After 2 years of incessant cries of help from Churchill.
