And let's not forget, that had he stayed on the throne, the fact that he and Wallis never had kids would have landed Elizabeth on the throne anyway. However, her mother would not have been the Queen Mum.
I think the Queen Mum has always had a hatred of Wallis but to blame her for the death of her husband, who died of lung cancer, is really not to acknowledge the truth of what cost him his life. And it is sad that Princess Margaret's heavy smoking cost her her health too. I would bet she smoked out of rebellion. Someone earlier stated it had to be hard to be the "spare". They might be on to something there. Look at what has been going on with the current " spare", Harry.
Excellent point. In fact, some conspiracy-minded historians have suggested that the whole Wallis Simpson business was just a convenient pretext to force his abdication, the real reason being his unsavoury political views. You're right about it being unfair for Elizabeth to blame Wallis for her husband's early death, but that is apparently how she feels, and it's something Margaret would have had to take into account when deciding whether or not to follow the same path as her uncle.
