Hitler wasn’t interested in Moscow, it was all about getting the Caucuses oil fields.
However by taking Moscow, it could have very well resulted in the collapse of the Soviet government, certainly Stalin was on thin ice as it was. Stalin made a lot of enemies, and once they overcame their fear of him, it would have been only a matter of time before Stalin got his, and new leadership took over. Who knows they may have even abandoned Bolshevism in order to unite the country against Hitler. Then we would have had the best-case scenario. No more Nazism nor Bolshevism.
Japan should have taken the Hawaiian Islands on Dec 7th. Then taken Australia. War would have taken a long time.

Hitler absolutely wanted to take Moscow, because not only was it the capitol, it is a very important transportation hub. Without Moscow, the Soviets would have had a hard time shipping supplies and soldiers around, because all the railroads connect in Moscow.
