We’ve seen a positive outcome to the climate change talks, and now an agreement at the UN in the Security Council for a peace plan for Syria. It’s not just the agreements themselves but the willingness to argue and discuss and actually reach agreements that I find encouraging. Both are under the auspices of the UN. And both have come about because of the engagement of all parties. China now fully recognises the urgency of measures to combat rising CO2 emissions, so too the US administration, if not the coalheads behind the American far-right in Congress. And Russia is now fully engaged in the Syria peace process, seen by some in the West a few weeks ago as a backward step, but as an interested party committed to the support of the Assad regime, with a naval base at Tartus in Syria, essential if a peace process was to move forward.

One reason for the failure of Obama’s attempted rapprochement with Putin was the fact that it was one-sided. Putin has now established himself, as he’s wanted all along, as an ‘equal’ partner. 2003 the US and UK tried to call the tune, and that can’t be the way forward anymore. We don’t have a democratic Russia, as we all hoped for after the fall of the Soviet regime, but we do have a government with whom we can deal and – possibly -reach agreement at a global level. We can establish areas of vital common interest and work out from there. Likewise with China: combating climate change has potential for being a major area of cooperation between China and the West. We can’t as yet resolve issues surrounding China’s imperial ambitions in the South China Sea, but working together in one area can only improve the prospects of doing so in others.

And there are serious – fundamental- issues of human rights. We have Saudi Arabia as an ‘ally’, and that’s pretty cynical in the scheme of thing. But we have to work from where we are. And what conflict tells us is that the big stick never works. So if we have to work with the likes of Putin, best to get on with it. Pragmatism is the best ally of idealism.

Another lesson – the importance of bodies such as the UN, above all the UN, under whose auspices the nations of the world can come together, and argue, and find common ground. Doing exactly what it was set up to do.

I’d put the European Community in the same category. What’s remarkable is that countries are working together, at a European – and a global level. War shattered Europe st  twice in the 20th century, and European institutions over the last sixty years have  cemented peace in a quite remarkable way. Walking away from the EU would be lunacy. Putting all our energies into reforming it so that it is and is seen to be an institution working for people at all levels is the only way forward.

And that requires strong leadership. Whether it’s Obama and Kerry, Putin and Sergei Lavrov, Hollande and Fabius, who acted as convenor at the the Paris talks – presidents and foreign ministers, the recognition of the interests of each of the parties involved is essential if common ground is to be established and agreements achieved.

This may be stating the obvious – but it’s why were getting agreements now, and we didn’t before.
