Of course, as an American, you're an authority on entering conflicts near the end, after all the hard work's been done, and claiming all the credit.
I am going to address this once because I am tired of seeing it and because Americans in general, raised under the post-Suez and post-Empire amity between our nations, aren't all that familiar with the international situation as it stood pre-war.
You guys were not, in any sense, our friends. On the world stage you were a giant bullying menace, allied with the Japanese(!) up until about 1920 or so as a way to maintain your naval dominance in the face of growing American strength. And, as I have said before, every Norwegian knows that you were literally days away from invading when Hitler beat you to it, such was your high-handed approach to the dignity of neutrals.
Americans have a long history of isolationism, i. e. staying out of conflicts where there isn't sufficient moral clarity, and, in the pre-war American mind there wasn't much to distinguish the imperial ambitions of Germany in both conflicts and the abuses to which the British had subjected a large part of the world. It's easy to miss in all the cartoon villainy of Allied propaganda but the agreement to dismantle the British Empire under the right of self-determination (extracted by Roosevelt in August 1941 while Churchill was over a barrel) in the Atlantic Charter is one of the greatest things to come out of WWII. In another world there would be some sort of monument along the Mall, maybe a triumphal arch surmounted by a statue of Uncle Sam deflowering a buxom Britannia while eagles shriek in ecstasy.
