Re: Britain has been a staunch ally to its NATO partners
It's worth noting that when Britain did attempt to bomb Germany in daylight in 1939, the bombers were generally decimated (actually, that's an understatement: I think on the Wilhelmshaven raid, losses were 100%).
Poland allied themselves to the largest Naval power on earth at the time, but a power that had a tiny army, none of which was on continental Europe (I think the initial BEF deployment was about 160,000, which is about 1/8th to 1/10th the size of the force that Poland had already mobilised). It took most of September to get that initial BEF into France.
Once in France, the BEF was deployed near the Channel coast, consistent with maintaining supply lines back to the UK, and(predictably) in the area it had operated in during WW1. The British army therefore had no actual route to 'get at' the Germans, without violating Belgian neutrality (The French and British wanted Belgium to cooperate, but Belgium followed a policy of strict neutrality until they were actually invaded).
Meanwhile, the Royal Navy was hunting down merchant shipping and merchant raiders belonging to Germany, and instigating a blockade (everyone always seems to remember the U-boat campaign against Britain in both wars, but forgets that the UK blockaded Germany in both too, particularly effectively in WW1, but not without effect in WW2).
In respect of the UK, Poland allied themselves with a Naval power, and got an immediate (naval) response.
Whether the French (as a more 'continental' power) could have done more
