If 2nd front was before 1944?

that's a question that still burns to this day.
of course the Allies knew what was going on with Auschwitz, Treblinka, etc.
Escapees from the camps got to the UK and told Churchill what was going on.
and it was admitted recently that plans were drawn up to bomb the camps but they couldn't be sure they'd hit the gas chambers and not the prisoners in the main camp.
(that's their offical excuse too)
i don't know. I've heard theories that it was virtually impossible to fly bombers to Auschwitz and back on account of the distance. but Buna was bombed and with it Auschwitz but not intentionally.
the worst theory i've heard from several sources was that the Allies knew what was going on over in the 'east'. but as long as it was Germany's signature on the dotted line, that the blame for mass genocide would fall on the Nazis, why don't we let them get on with it. We stall aid (be it invasion or bombing) until we have no choice and play the hero for those prisoners who are still alive (hopefully not too many though).
I hope to G-d, with all my heart, that that is not true. but i don't know.

does it rank right up there with the JFK assisnation and the 9/11 'controlled demolition' as insane theories?
Probably. but from what i've read over the years i cannot find many justified reasons for not bombing the camps especailly hfter their locations were known. and that really sucks.

The Japanese and the Soviet Union had a couple of border skirmishes in the late 1930's in Manchuria. The Japs had thier asses handed to them by the Russians so they weren't too keen on taking them on big time. Despite the "Pact of Steel" that Japan signed onto with Germany and Italy, they left Russia alone, much to the disgust of the Germans who were counting on the Japanese opening an Eastern Front in Siberia.
As to America invading Europe before 1944. First off, even before Pearl Harbor, Roosevelt decided "Germany first." We engaged the Germans in 1942 in North Africa and, after getting OUR asses handed to us at Kassering Pass, we eventually brought about the surrender of over a quarter of a million Germans in Tunis in May, 1943. It was described as a "second Stalingrad" We tied down many German divisions and industry in Italy.
The biggest delaying factor for the Invasion of Northern Europe was landing craft. We simply did not have enough. What we had and what production was geared for was for Europe. The Pacific constantly had to take a back seat in Equipment and men.
Admitedly, the objective of the War for America was not saving the Jews, but the destruction of Nazi Germany. Our State Dept. had a shameful history pertaining to the Jewish plight in Europe(as it has today for the plight of Israel) As we recognized the scope of the Holocaust the leaders felt that the best thing we could do to stop it was bring about the destruction of Germany. Yes, we could have done more, bomb the rail lines leading to Auchwitz, publicly layout what the Germans were doing in detail, but, Mr. Armchair General, 60-odd-years-on, how were you going to convince Hap Arnold to divert planes, bombs and risk the crews to attack a concentration camp in Southwest Poland? The Air Corps did bomb the Farbin plant at Birkenau. With 20/20 hind site, we can all see what we should have done. But we did what we did, good and bad.
If you want to blame people, try blaming England and France for not taking the dozens of opportunities, before and during the War to stop Hitler and keep 12 million human beings from vanishing into the night of Man's inhumanity.
As we listen, today, to anouther "funny-looking" madman publicly anounce nuclear genocide, we still resist doing the right, if difficult, thing. We make excuses, we use anti-war propaganda to stop us from stoping Iran. I've even read some blogs that ask why the big deal, they're only Jews. And in 2060, when Israel and Iran are nuclear ashtrays and people are bemoaning the "23 million" lost in the "Iran/Israeli War"; why didn't we, the people of today, do something to stop that squinty-eyed madman in Theran? Like our fathers in 1933, we have the answer, not the will.
