2 million killed where they lived? Again the Jewish people just hung in there and got themselves killed. Way to go Nick. Way to disrespect Jewish people of the 40s.
What is disrespectful is your utter ignorance of the history. The victims were trapped behind German lines and closed off in ghettos. That was after sizeable percentages had fled, some to safety and some who ended up overrun by the Nazis.
Kiev had 200,000 Jewish inhabitants before the war. When the Nazis arrived in September 1941, there were about 35,000 left. The rest had fled, because they'd heard about Nazi shootings, and because they were evacuated without preference or favour as part of the Soviet evacuation of workforces and industry to the Urals.
More than 1 million Soviet Jews were evacuated or fled out of the area that was to come under Nazi occupation. 2.5 million died in the same region or were deported. That means close to 30% could escape.
Most of the Jews in the Soviet Union lived on the western borders. They didn't have much of a chance to flee anywhere when the Nazis first arrived. Most were then fenced off in ghettos guarded by men with guns. But that didn't stop them trying to escape when they realised what was happening. 25% of the Jews trapped in the Volhynia region in Ukraine tried to escape the shooting actions. They were then hunted down in ones, twos, 10s, and killed. They were lucky - there were at least some forests nearby. Most of Ukraine is steppe, without forests to hide in.
Same pattern in Poland. 300,000 Polish Jews fled east across the Nazi-Soviet border in 1939, before there were really large-scale killings but when they knew that life under the Nazis would be unpleasant. Then the border was closed and they couldn't escape. 10s 1000s more fled inside Nazi occupied territory, 100s of 1000s were expelled. Then ghettos were erected and they were prohibited from moving anywhere. From late 1941, the penalty for being caught outside the ghetto was usually death, from late 1942 it was always death.
But that didn't stop lots of Jews from trying to flee and hide in the forests or go underground in the towns. The catch was, it was very difficult to survive in hiding. Polish Jews knew this, they knew they could not all blend in and keep themselves hidden. How would they all feed themselves? How could an entire ghetto like Warsaw with nearly 400,000 inhabitants hide themselves outside the ghetto? 10s of 1000s did, but expecting 100% to have done this is poppycock.
