* A rousing public speech is very different from actual policy. A sibiling comment to yours make reference to a plan by the Japanese, made in secret and actually started, that was known to cost millions of Japanese lives and wasn't even meant to secure victory but just better surrender terms. Your quotation doesn't come close to showing that the British would be prepared to do something similar. (In fact I'm sure I read about a plan Churchill had to surrender if Germans did make it onto British soil, but I'm not going to search for it now - the burden is on you to show that the British wouldn't have surrendered.)
* Aside from broad policy, the difference in attitude is clearly shown by actions of individual soldiers. Individual Britons in theatre would usually be prepared to surrender if their situation was hopeless, as shown by the number of actual British PoWs in WW2, whereas this was much rarer for Japanese soldiers.
