Yes, the war actually started with both Germany AND Russia invading Poland.
No, Germany haven't invaded the rest of Europe, in case you've forgot, both Britain and France declared war against Poland invaders (though not on Russia..), so actually Germany was in a state of war with France and Britain.. so, that's not an invasion (as in we've invaded them over night), but a legit part of the war actions.
Yet.. DO you know about this little declaration?!! Read it carefully please, and go dig it into the war magazines archives in case you think it's forged:
"
Poland wants war with Germany and Germany will not be able to avoid it even if she wants to." (Polish Marshal Rydz-Smigly as reported in the Daily Mail, August 6th, 1939)
What if actually Poland was acting as the small thug, knowing it has binding treaties with other two BIG thugs (read France and Britain) to jump in for it, no matter what?!!
There are voices saying that actually Poland was salying german population from the german territories taken from Germany and given to Poland at the end of WWI, and that was actually the reason for which Germany invaded Poland.. read
Polish Atrocities Against the German Minority in Poland, and read it full, not just the main article in there
Things are much more complicated than they are presented to us by "official history"..
PS: also, there's another thing I keep hearing in this "if Germany would have won, history would have been very different".. implying it would have been much worse than the actual outcome.. yet.. I find this disturbing.. are you VERY SURE things wold have been much worse?
have any of your big-mouths-stating-this-bold-declaration countries spent the past 50 under the paw of the communist russian bear?!! do you have any idea what was like to live in eastern Europe from 1945 to 1990?!! Germany killed 6 millions in concentration camps, official record (which actually might be a much pumped-up number), but do you have ANY IDEA how many of my eastern europe fellows died in russian gulags?! the 50 millions number tells you anything?!! do you have any idea what happened in the countries and towns occupied by the soviets at the end of WWII?!! has the word mass rape any meaning to you?!! do you know that whole industries were dismantled from these countries and went to the brother russian as war compensations, leaving east european countries with nothing?! and then enslaved for the following 50 years to pay ten times the named war compensations (namely at the "fair" prices imposed by the russians)?!!
I'll tell you just one story, I've heard it countless times from all the elders I've talked with which were living those times.. when germans came, if you had two pigs, they would have taken one, and eventually give you something (no matter how symbolic) in exchange for it, and leave you the other.. when russian came, they would have taken both pigs, rape your wife and daugthers, take anything which could be carried away and eventually set everything remaining on fire..
THIS was your better alternative..
