Why invading Poland?
Poland was a very unpleasant regime. Just because Britain supported Poland doesn't mean they were a nice democratic, civil nation. Just before they were invaded they were killing people in Auschwitz and invading Lithuania. They also killed many liths in some horrbly nasty ways in vilnius etc. Supporting the Polish was a bit of a joke after the British helped Czechoslovakia get invaded. Czechoslovakia being a democratic nation that wasn't particularly nasty to anyone.
I do see your point, that if they want to be absolved of guilt they should have started a revolution. What about the children!! the poor Children!!!
