Foreign Affairs — The leading magazine for analysis and debate of foreign policy, economics and global affairs.
The United States under Trump has become a predatory hegemon. It is a strategy that contains the seeds of its own destruction. I explain why in this forthcoming essay of mine in FOREIGN AFFAIRS (no paywall but you do have to register). www.foreignaffairs.com/guest-pass/r...

German Foreign Minister Johann Wadephul at the IISS Raffles Lecture in Singapore today: "The law of the strongest seems to be increasingly replacing the strength of the law."

The second clip gets into the UK-US angle and the question of whether the UK is hedging. 2/2

Spoke with Steve Lai on the BBC earlier about the domestic politics surrounding Keir Starmer's trip to China, and the question of whether it connects to broader transatlantic tensions with Donald Trump. 1/2

The fear of spheres | Patrick Porter | The Critic Magazine
Periods of international tumult, like the present, need careful analysis. Solutions are no good, obviously, if one wrongly defines the problem. And in turn, careful analysis demands precision with one...
Excellent article in the Critic by @patporter76.bsky.social. I made a similar argument at an RSIS conference in Singapore last week - the underlying logic seems to be "spheres for me, but not for thee". If so, suggests more continuity than change in US foreign policy. thecritic.co.uk/the-fear-of-...

Doubting U.S. resolve, Europe looks to bolster its own nuclear arsenal
The discussions have taken on new urgency as President Trump escalates his criticism of Europe. Germany and Poland already have suggested France’s nuclear weapons could be expanded to defend their cou...
"'We are discussing how to protect Europe with a nuclear deterrent with or without the United States,' one of the European officials said. Another described the discussions among European leaders about ways to guard against a nuclear-armed Russia without the U.S. as 'intense and productive.'"

For reasons unknown, my first book, British Grand Strategy in the Age of American Hegemony, is on sale for £28.99 on Amazon UK - a 62% reduction in price! It would be rude not to at that discount! H/T to @jfb1066.bsky.social www.amazon.co.uk/British-Gran...

Re my book - that's v kind of you. It's rather pricey unfortunately (my editor tells me that the market for academic books has flat lined), but here is a discount code if you order directly through OUP: ASFLYQ6. Looking forward to hearing your thoughts and hope to catch up on my next trip to 🇬🇧 4/4

point on process. Some are obv better than others. CID & SWW committees are already mentioned here, but I think the Defence & Oversea Policy Committee was a decent forum in bringing the right people together. You can see the difference when Blair gets rid and you have a poor GS decision on Iraq. 3/4

you mention. The East of Suez example comes to mind - there were numerous papers between ministers and officials discussing the problem of overstretch & the need to balance means and ends, but it was difficult to implement (and was ultimately botched by a currency crisis). Also, I second your 2/4

That makes sense. If I've understood correctly, you're mainly talking about the gap between conceptualisation & implementation. If that's the case, I fully agree - I think it's perfectly possible for govts to conceive of 'good' grand strategic decisions but fail to execute for all the reasons 1/4

If we go back to early C20th thinking on grand strategy, it was about a level of decision-making with *long-term consequences*. That lens still travels today (e.g., AUKUS as a grand-strategic decision). Some of us are still trying to keep that flame alive - perhaps in vain 😅 2/2

Respectfully disagree, but I think this comes down to interpretation. The idea that grand strategy = long-term behaviour across successive governments, grounded in fixed interests largely derives from Paul Kennedy. That framing is problematic for several reasons, many of which you rightly flag. 1/2

To Greenland and Back
Does NATO carry on as before?
Latest post tries to catch up with the back and forth on Greenland. I argue that rather this being a rupture (as Mark Carney suggested) the European response shows a transition to a rebalanced transatlantic relationship with diminished US power. (£/free trial), open.substack.com/pub/samf/p/t...?

Military archbishop: Troops could refuse orders on Greenland
Speaking to Britain's Sunday program on BBC, Archbishop Timothy Broglio reiterated that conscience could permit refusal of an unjust military order.
It’s come to this: “Catholic members of the US armed forces could in good conscience consider disobeying orders to attack Greenland if such orders were issued, according to Archbishop Timothy Broglio, the bishop responsible for the pastoral care of US military personnel.”

Thatcher wrote in her memoirs: “I was to have many disputes with President Mitterrand in later years. But I never forgot the debt we owed him for his personal support throughout the Falklands crisis.”
Defence Secretary John Nott: “In so many ways Mitterrand and the French were our greatest allies”.
