2022: the year of insecurity – Ukraine, Taiwan, Ethiopia, happening against a background, as my last blog post set out, of record military spending, with refugee numbers already at a record high. It is tempting to think that this means we need to junk woolly thoughts about human security and suchlike and get back to old-style basics, in which security lies in a strong defence, in power, to be blunt, and more of it than any adversary has. It’s what is called realism in the study of international relations and the realist temptation today seems strong.

It is the direction in which the Russian invasion of Ukraine and the confrontation between China and the USA over Taiwan seem to be pushing us. A return to realism, hardening up NATO against Russia, though it’s worth acknowledging that the demand to get Western policy ‘back to realism’ is a long-standing idea . But why ever and whenever, it’s all about recognising that, if you get into trouble, only the exertion of power will get you out and that’s how it’s been for thousands of years.

Mm-hmm, except that 2022 is also the year of climate change: drought in China and Europe, floods in Pakistan, both in the Horn of Africa, unfolding in a context of several other aspects of serious environmental deterioration, as my last blog post also set out.

And since this means that the mix of challenges on today’s security horizon is not only complex and worrisome but also unprecedented, it suggests there is a need to think hard about what we mean by security – the security of whom or what, and against what – and, indeed, to be ready to rethink.
