If, as seems increasingly likely, the astonishing events in Salisbury are state-sponsored, how should the UK respond to this outrage. Assuming evidence emerges that links the murder attempt to Russia, is there anything we could do to punish that country?
At times like this it would be comforting to look to the EU for support, collectively led by Federica Mogherini, the High Representative of the European Union for Foreign Affairs and Security Policy. For reference, Federica Mogherini, who does not appear to have ever worked for a living, was a member of the Italian Communist Youth Federation from 1988 to 1996. A spokeswoman of hers is married to a communication adviser to Gazprom, the Russian owned energy company and the largest supplier of natural gas in the world. Perhaps it is unrealistic to expect a robust reaction from her?
We could hope that individual Nations may be more sympathetic. Germany, for example should surely feel threatened by an aggressive Russia. But then, having shut-down their nuclear generating capacity and under pressure not to reinstate any more coal-fired power stations, they are dependent upon Russian gas supplies and are unlikely to poke a stick in Putin's eye.
How things have changed. In the mid 1980s I held a staff appointment at a NATO Air Headquarters at Ramstein, near Kaiserslautern. The geography was idyllic - the Black Forest, Switzerland, Alsace, the Moselle Valley were all close by - and, with threat of mutually assured nuclear destruction apparently working and keeping weekends free for leisure, there was plenty of time for recreational travel. However, that easy-going life concealed a harsh reality beneath. My boss, Manfred, a steel-eyed Prussian, and all his German colleagues were under no illusions about the threat we faced. War games were played out very seriously indeed and, depressingly, most ended in a furious nuclear exchange. Before that strategic destruction, however, my German colleagues would have been quite content to loose off the odd small nuclear weapon to stem the advance of Warsaw Pact armour surging through the Fulda Gap and pushing through the Inner German Border towards Frankfurt - they knew what was at stake and they meant business.
But that was 1982 and, despite Crimea and Ukraine, perceptions of the Russian threat have changed today. Desperate to believe that our opponents will always view problems with our smug Western bias, our politicians cannot bring themselves to admit, at least in public, that Russia poses a threat. So, noble though it is, the Duke of Cambridge deciding not to go to the world cup is not going to cut it. Neither will PNGing a handful of Russian diplomats of freezing the assets of a few criminal oligarchs. As Corporal Jones remarked, however, they don't like the cold steel up 'em - if we want to make an impression on Russia, we need bigger and better bayonets. We should immediately commit the funds necessary to restore the operational integrity of our neglected armed forces and urge our NATO allies to do the same. That is something Putin would understand.
