65th Aniversary of the RAF's raid on Dresden

don't ban him.
tell him to go for a bike ride round the fields of northern france and flanders*
there's quite a few things to see there that would make you think in a different way about the war instead of intellectually theorising about the nazi winning majority and Britains bombing policy.

*i want to do this. always wanted to go to the memorial graveyards though not sure why.

Also cycled to Ypres. This is the Menin Gate. It is dedicated to the Commonwealth soldiers killed in WWI who don't have known graves. Since 1928 every night at 8, they play the Last Post. It's a very moving experience. The surrounding area is also well worth cycling around. There's lots of memorials and preserved/recreated examples of trench warfare life..
