Nau mai, haere mai.

As luck would have it, my return to work coincided with the second inauguration of Donald Trump as US president. The end of a holiday break was certainly the more predictable.

If I was a betting person, I’d have put good money on living through only one Trump presidency in my lifetime. The extraordinary events of his first tenure, from the pandemic response to an attempted insurrection after he lost in 2020, seemed at the time to guarantee that.

But these are not predictable times, and many old assumptions have been laid to rest in the past months and years. We’re no doubt all taking stock right now, but we do at least have the benefit of recent history as a guide to how Trump 2.0 might behave.

Chris Ogden describes Trump’s instinct for what has been called “weaponised chaos”, and how this manifests as a “political shock doctrine” that is a “blueprint for current and aspiring autocrats across the world”.

And Nicholas Khoo explains why Trump may be unique among US presidents in his potential to “strike greater anxiety in allies than in adversaries”. But in calling out the supposed “free-riding” on defence by traditional US friends, Trump oversimplifies the complex dynamics of alliance networks – and American power.

The 47th president has said “America’s decline is over” and promised a new “golden age”. The next four years will be the judge of those particular predictions, for better or worse.
