The First Real Peace Settlement after the First World War. Why we can still learn a lot from the Locarno Pact - after 100 years. My latest essay for Engelsberg Ideas: engelsbergideas.com/essays/the-l...

I've written a piece for @engelsbergideas.bsky.social on the sources of grand strategic ideas. Best enjoyed over the weekend with a brew ☕ Thanks to @jackfdickens.bsky.social, @paullay.bsky.social, and the EI team for publishing.

Should the UK and Japan have a new formal defence alliance? On this question, I agree with @wdjames.bsky.social that "rather than engaging in lengthy treaty negotiations, Britain and Japan should focus on tangible outcomes, such as delivering GCAP on time." www.britainsworld.org.uk/p/the-big-as...

Do 🇬🇧 & 🇯🇵 need a formal defence alliance? My view: They’re already building an entente - providing a degree of reassurance & deterrence. Better to focus on delivering GCAP than spend political capital on a time-consuming treaty. Thanks @congeostrategy.bsky.social for inviting me to pitch in #BigAsk

"Strengthening European nuclear and conventional capabilities, through more Franco-British cooperation among other things, is not simply a desirable option. It is becoming an unavoidable necessity." warontherocks.com/2025/09/can-...

My most recent piece for the Council on Geostrategy tackles how military alliances can relate to strategic advantage.

Delighted to see my book featured in @warontherocks.bsky.social. Thanks, @salisbot.bsky.social!

Prof John Bew recently reviewed a new book for the Times Literary Supplement. He discusses how, amid debt, manpower shortages, and fears of Soviet domination, Whitehall sought to preserve Britain’s influence in a fragile postwar world. Link to the article: www.the-tls.com/history/twen...

With the recent flurry of diplomatic activity this past week, there has been renewed interest in the proposed 'Multinational Force Ukraine'. I write here on the proposed structure of this Reassurance Force, its pros, cons, and the question over its strategic utility.

"The real test of a book is if and how it generates responses, extension, and even controversy...One hopes that British Grand Strategy in the Age of Hegemony will generate a substantial body of related scholarship." Thanks to Prof. Peter Dombrowski for this generous review! tinyurl.com/yacdwwb7

📝 "This was not the first time Trump found himself at odds with MAGA purists urging isolation and retreat from foreign adventures," writes Dr Shiraz Maher in his latest piece for @engelsbergideas.bsky.social

It was a pleasure & an honour to assist the 🇬🇧 High Commission with several panels on regional security & maritime strategy on HMS Prince of Wales last week, melding Southeast Asian & European expertise. Thanks to Cdre Blackmore & the crew for hosting - they more than earned their 'run ashore' in 🇸🇬!

Just finished the last episode of The Wargame. Pretty sobering ending - Russia definitely got the better of the exchange, even if the game finishes mid-war. An excellent way of bringing the dangers of our present age to a wider public, not least the UK's very limited response options.
