What did Chamberlain do?
If you are going to try to make a point you should know what you are talking about. It is amazing to see Chris Matthews actually playing Hardball.
I am tired of people invoking history that they are ignorant of. I really do believe that if we do not learn from history we are doomed to repeat it. I hope that we see more media-types require their guests to actually know what they are talking about. Maybe facts and history will make a comeback.
If you want the full answer, a quick Google search will yield the BBC page about Mr Chamberlain [here].
