Foreign policy Shatners

As we appear to be about to embark on another ill-considered war, this list of 20th century US foreign policy mistakes (he calls them Shatners for reasons explained in his post) from Dan Drezner is particularly apposite.

I would drop the one about the League of Nations and replace it with one about entering World War 1. I would replace one of the others, I am not sure which, with the failure of the US to open its doors wide to immigration by European Jews during the 1930s.
