i have been reading articles / stories about world war 2 on the net. watching movies like saving private ryan and the longest day made me curious about lots of things! too bad that the information i found so far after 3 days of browsing is not very coherent, i felt like there are too many plot holes... i have a few questions that hopefully would be answered by some history buffs on htf, thanks in advance. 1- why did america have to nuke japan? 2- why did they choose for D Day attack instead of nuking germany? 3- why did hitler hate jews? why not any other race? 4- how did the german create the war mahines? they were lost on world war 1, but then they returned for war with a vengeance!
