Why has British defense underinvestment not become a scandal?

Why has British defense underinvestment not produced a larger political reckoning?

The costs remain easier to defer because Britain has not yet suffered a single unmistakable military disaster that forces public attention.

In this interpretation, visible procurement problems have not yet become a national crisis. Many people can see the shortcomings, but no single shock has made them impossible to ignore. Governments may wait until losses impose the lesson rather than building resilience beforehand. Political attention therefore turns on whether a state funds capability before or after a preventable emergency.
