No it isn't, you cannot make a nuclear bomb that weighs a bit more than a big girls hand bag. If you want to show me handbag sized nuclear weapons from the 1940s I am very interested but I know, since I worked as a qualified radiographer, that such technology in ionising radiation didn't exist in the 1940s and actually doesn't exist now.It is completely within the realm of verification. This whole "it's my opinion so it is also true" nonsense is asinine. Historical analysis is subject to academic assessment and peer review. Someone posting speculation (or pro-Nazi propaganda) does not constitute a rebuttal to researched and published work.
