Is there something special about British stiff-upper-lipsness?

I'm not saying the Brits are any better than anyone else on this planet but I think it's fair to say that there is something stoic stubborn Churchillian-like all-together been-through-the-Blitz God-bless-the-Queen about the people of Great Britain which is possibly uniquely helpful in surviving this deadly Coronavirus pandemic era. OK, we're a small but heavily populated country with a glorious past but history shows that the Brits never give up. We also, or most of us, honour and respect and love our Queen and listen when she tells us that life will get better again, and we also know from people of the oldest generation that in the gravest moments in our history, like World War 2, there was an incredible spirit in the country, a determination to make do and adapt while the bombs were dropping. The Blitz thing can be overdone. After all that was 80 years ago, but every schoolchild knows the story even if they find it hard to grasp. We have had so many wars since but none of them actually threatened our shores, while other poor countries have suffered and are suffering terrible wars. Syria, Iraq, Yemen, Sudan, eastern Ukraine, Democratic Republic of Congo, Mali, to name some of them. The civilian populations of these countries have to fight to survive every day but do they have anyone, a leader, a monarch, a church leader who can unite them and give them hope? I don't think so. And I feel desperately sorry for them. For this particular blg I am writing solely about the coronavirus pandemic and the way countries have coped and remained optimistic. Countries like China, Germany, South Korea and New Zealand have rigorously enforced the strictest possible measures and testing programmes and have benefited by restricting the number of deaths. New Zealand is the most remarkable, with only four deaths so far. We in Britain were a bit slow in coming out of the starting blocks but we're getting there and it's beginning to work. But it's the spirit of the country I'm writing about. The British spirit which is alive and well is going to bring this country out of the mess and into a better future. The Queen's address to the nation, perfectly timed and perfectly scripted, and the Prince of Wales's televised words to the country which were also softly spoken and nicely comforting, helped millions to come together. Strangely, although not strangely, the hospitalisaton of Boris Johnson has also helped to unite the country, We all want him to get better. The tiny few who have spouted appallingly horrible messages about Boris and his health battle have been swiftly stamped on. My "other country", the United States where I lived and worked so happily for three years, doesn't really have the same set-up. I think it would be fair to say that President Trump is not a unifier like Her Majesty Queen Elizabeth II, and the country remains divided by all kinds of things. It's also huge, so much more difficult to unify I admit. But there is no single voice which makes every American citizen feel warm in the heart. I don't want to over-romanticise the situation here in the UK, but I think right now we are pretty united in our amazement at the sacrifices being made by our National Health Service, at the grit of everyone facing tragedies, and our faith in the Churchillian spirit that helps us get up every morning.
