It is good to see Jonathan Freedland calling out the thuggery of the Trump administration (Donald Trump is pursuing regime change – in Europe, 12 December). To safeguard its security and values, Europe must act swiftly to prepare for a post‑Nato Europe. Such thinking also generally proposes major increases in military spending, an EU-based command structure independent of the US, integrated European military capabilities, a shared European nuclear deterrent, and binding mutual defence commitments. However, recreating a European-led “house of dynamite” will simply compound existing insecurities. While challenging to implement, a compelling model for sustainable security without nuclear deterrence or offensive military capabilities could be developed.
