I don't think so. We've got unhinged leaders of both Russia and the USA. China is also becoming a dominant superpower in terms of economy and military. Even if the UK isn't directly impacted by war in terms of military damage/invasion, our way of life and economy could easily be badly impacted by trade route blockages etc/. as seem during covid, the suez blockage and now the oil tankers being blocked. The cost of oil is rocketing which means shipping goods from China to the UK will be more expensive, plus carriage/delivery of goods, plus food production costs due to fertiliser cost increases, etc.
National debt is close to the highest in living memory. It's decades since we've had a surplus, so the debt is just getting bigger and bigger, even in Gordon Brown's "good times". We spend more on interest than education.
AI is looming which WILL mean even more unemployment, on top of the current increasing unemployment, very high youth unemployment.
More and more people reliant on benefits, fewer proportion of population actually working and paying taxes. More and more elderly people compared with workers, meaning more costs of pensions, healthcare, social care, etc.
The UK is reliant on other countries for most things these days, food, power, oil, etc., so we're very fragile to World events. Go back a few decades and we were more self sufficient - yes, not fully self sufficient, we never have been, but certainly not as reliant on other countries as we are today!
Everything is heading in the wrong direction with no glimmers of hope at all.
