If I switched on the news tomorrow and the headline is “The USA has bombed…”, any country or continent could be at the end of that sentence and my surprise (or lack of) would be the same.
The USA is being run with no guard rails by a deranged dictator, backed up by white supremacists and corporate robber barons. Any country is fair game including NATO members, in response the UK should switch to a war economy.
No, war would be an entirely different experience.
As it is, everyone is still talking in strongly worded letters, every day life is business as usual. There have been basically no consequences for the economy, trade and travel are still happening mostly normally (I think tourism is down less than 10%). There are no emergency taxes, restructuring of production, no draft…
If you think this is bad, you need more context, look at actual regions affected by war and compare your nearest cities to that.
Let’s not get into a “my war is better than your war” contest. In the mind of a demented dictator we may already be at war with him, it’s prudent to prepare for that, or any country may be caught off guard.
