Well first of all my name is not Director, that's someone else. And I kind of disagree with that, it's not like the allies just went "here ya go Hitler have some tasty Czechoslovakia and Austria". They didn't exactly have a choice and instead of going for the costly war route, they decided to be diplomatic in order to stop further German expansion. Of course that didn't work but how an earth were they supposed to know?
The Soviets on the other hand didn't just allow the Germans to take territory, they actually very actively helped them with economic, diplomatic, and military co-operation, I.E Poland.
I'm not saying the Allies were innocent, but they certainly didn't help the Germans nearly as much as the Soviets, which then ironically went onto be the Germans worst enemy.
actualy they did have chose, even churchil in 38 told "we did have choice betwen shame and war, we chosen shame and will have war".
and did you heard about one small, unimportant book called main kampf writen by hitler ? its english/france tranlastion was avaivable waaaay before 38. and here hitlers goals were nicely stated.
and why western didnt acted ? because his goals were liked by thier political leadeership and fited to thier goals, but they simply ignored danger hiden there.
chamberlain "peace for your time" was not only driven by wanting peace, but it fited his view of world politick, since he and his party wiewed stronger germany (at expanse of eastern nations) nice counterwheight to france power, and if frnace have to worry more about thier land in europe....it will weaken thier position outside of europe, serving in interes of british empire which can be maken stronger here.
they were simply blind in that that hitlers germany can turn against west - them. since 38 relationship of british ruling party and geman ones, were more of friends than of enemies. just look how uk king (cant recal his name, that one which was forced to resigh because he maried divorced american woman) were very pro-german and how he admired hitler. and look how hitler tried to make peace with britain in 40, after fall of france.
i personaly think if in uk in charge was this king and chemberlain ideological succesor....it will be great posibility.
and what was result of this stupid "we dont care about your eastern allies" policy ? lose of british empire, which was only logical, since uk was unable to fight japanese when they have hands full figting germany, and losing of "white superiors" to "asiatic inferiors" showed to british colonies, they can win against them too, taht they are not superior, so they wanted independce, and the got it.
and for soviets, yes they cooperated with germany booth military and economicaly, but hey whcih major state DIDT economicaly cooperated with germany, until they were at war with them ?
just look at swedisn iron send to germany during whole war. and just google how many vehicles/resources us (ford is nicest example) sold to hitler before war between tem. hell, even ibm was selling tabulator machines which were used in concetration camps.
