Britain didn't stand alone from 1939-1941 though. That's just a myth spouted every year at Conservative party conferences.
If by standing alone you mean the British Commonwealth then you are quite correct. If you mean Britain standing alone then you are quite wrong.
Millions of Commonwealth troops would disagree with you. Not to mention the considerable numbers of foreign pilots who defended Britain during the Battle of Britain, or the Americans who helped arm Britain during her 'darkest hour'.
Without Britain declaring war on Germany in 1939 none of the Commonwealth nations would have taken up arms. When Britain found itself in the vanguard, plenty of foreign nationals came to Britain and took up arms against the Axis, that does not mean that those individuals were representative of their own nations. Plenty of Americans joined the RAF but that doesn't mean the US declared war 1n 1939. France reneged on the Kasprzycki-Gamelin Convention and despite the fact that they too declared war on Germany in 1939, they did nothing to support the Poles despite promising to do so. If you want to be pedantic then I would say Britain and the Commonwealth stood alone, but Britain and the Commonwealth Armies were basically one and the same because without Britain (as I have already explained) there would have been no Commonwealth armies.
The clangers didnlt have anyone fighting their corner either but you never hear them bragging it about.. How the Soup Dragon didn't get some form of military award for keeping his planet safe from the tyranny of Nazi Germany is beoynd me.
Hardly but you are close. Finns stood shoulder to shoulder with Nazis because it was their only way of getting supplies to fight off a russian invasion.
