I think we are fortunate in many ways that we live in an age of electronic communication - the internet has enabled people from all nations to talk to each other and it is not as easy for propaganda to fool the general population in the way that Goering described.

(From a post I made on another thread)

"Why of course the people don't want war. Why should some poor slob on a farm want to risk his life in a war when the best he can get out of it is to come back to his farm in one piece? Naturally the common people don't want war neither in Russia, nor in England, nor for that matter in Germany. That is understood. But, after all, it is the leaders of the country who determine the policy and it is always a simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked, and denounce the peacemakers for lack of patriotism and exposing the country to danger. It works the same in any country."

Hermann Goering

If this country were truly threatened then I have little doubt the general population would 'rally to the cause'.  The other side of the coin though is that it is more difficult for conscription for a cause that was not seen as justified by the people to be enforced.  The politics that led to WWI would never have gained the support of the people if they had been privy to all the details.
