The Prime Minister has once again assured the nation that he is prepared to make difficult decisions at next month’s Budget—a statement that, in political terms, means approximately nothing and everything simultaneously.

What makes this particular promise remarkable is the sheer confidence required to deliver it while simultaneously rejecting any suggestion that the government might, in fact, be engaged in tax-and-spend governance. It is a neat trick: promise hard choices while insisting you are not making any choices at all.

The public, meanwhile, has been waiting for these difficult decisions since roughly 2010. They have grown so accustomed to the phrase that it now functions as a verbal palate cleanser between election cycles—something politicians say before doing the opposite, or nothing, or occasionally both.

Here is how the magic works: announce that difficult decisions are coming. Watch public anxiety rise. Deliver a Budget that either cuts services in ways nobody notices immediately or raises taxes on groups too small to matter politically. Declare victory. Repeat next year.

The real difficulty, of course, is not in making the decisions. It is in explaining to voters why their taxes went up, their services got worse, and somehow this still counts as restraint. That requires the kind of rhetorical gymnastics that only a prime minister—or a magician—can pull off.

Next month’s Budget will likely follow form. Difficult decisions will be made. Nobody will be satisfied. And by 2027, we will hear the phrase again, delivered with the same straight face and the same implicit promise that this time, things will actually be different.
