famous people who died from smoking never take it up?

   Friedrich III would definitely be a big change. George VI might also affect things if he lives say another decade and Elz II would still be waiting to celebrate her 60th year on the throne.

  On a more trivial level, although liver disease might well get him given his drinking, Bogart could well last longer and produce a few more films.

  Given how commonplace and often glamourised smoking was I suspect plenty of people, including a lot of ones who were influential, or even might have been would have lasted some time longer.

  Some of the language is rather strident and there are a couple of clear errors * but in general there is markedly less chance of a war developing as OTL.   You might have ended up with and Anglo-German-Austrian block v a Franco-Russian-Italian one, but suspect there would be less overall militarism and if such a war did come the central bloc is likely to be so much stronger and win fairly simply.

* by errors I mean

a)  The actual name of the dynasty was Saxe-Coburg not Hanover after Victoria's marriage to Albert.  In fact on one TV quiz a few years back William IV was described as the last Hanoverian monarch.  [Which is something I was dubious about although did some reading at the time on-line and that seemed to support the conclusion.  Still think it odd that Victoria wasn't considered a member of the Hanoverian dynasty, if only prior to her marriage]  Checking Wiki seems to agree with me but definitely by WWI the dynasty name wasn't Hanover.

b) In the run up to WWI Britain had a Liberal not a Labour government, although the author is correct that it wanted better terms with German to cut military spending and did cut back somewhat on it.  There were attempts at negotiation and most people think there was an unofficial agreement on the issue for the years immediately prior to the war.

  Definitely agree.  Remember, albeit about a decade ago one of the moderators on AH had 2-3 related TLs where there was a dominant Anglo-German alliance.  One where it was liberal, more where it went dark and militaristic and possibly a third somewhere in the middle.  Think the POD for at least the liberal one, and possibly the others was Friedrich not getting cancer.  Didn't realise until I read this article, should have mentioned in my earlier post, how easily his life could have been saved even then.

  The idea of Stalin living even longer is rather worrying to be honest.  A probably steadily more paranoid and nuclear armed Stalin is not a pleasant thought!
