First of all Nazis invaded Poland then Czech just to remind you all of beginning of second World War. Then Polish government was asking for help but Churchill turned his back and didn't not help but when there was shortage of British RAF Pilots guess what... Poland helped and thanks to them you have got your freedom but that's not all, after the war British government sent out a bill to Poland for the use of British military equipment how cheeky was that it was an absolute disgrace.
