that is blatantly false and it goes downhill from there.
Hell, the RAF attacked the German navy just days after declaring war which was just days after Germany attacked Poland....can you imagine the US being able to get moving that quick?
Within a month Brit troops were in Belgium and later France...and so forth. There was simply no way for Britian attack Germany directly in Poland and it would have made little sense anyhow.
Since the invasion of Poland was basically a “Joint Venture” with both Germany and the Soviet Union participating after agreeing on which would control what territory beforehand, why did the British and French let the Reds slide while declaring War on Germany?
Within a month the Brits were in France. That’s how they lived up to their pact to support Poland? LoL!
