Can’t even think why the UK need a defensive budget….
Probably because the entire world has a reason to hate the British government and the Crown.
Here’s a nifty little map, note the 22 countries that aren’t filled in are the only countries Britain hasn’t invaded.
Government intervention means blowback. Blowback means that your country has to constantly watch their backs. This means that they have to be armed to the teeth and constantly monitoring everyone in, around and sometimes thousands of miles from Britain.
This is also why America has a giant defense budget. Because we know just how much evil we’ve blanketed the rest of the world with.
