It has been common to say that the main strength of the US political system is its checks and balances. The three branches of Government are balancing each other out, and the free press and civil society in its many forms contribute with more checks on the system. Sometimes this is still true. But in many cases the result is dead-lock and a non-functional system. Most worrying is that in the fundamental case of war and peace, it simply does not work. This puts the whole world in danger.
The Paris summit ended with an agreement, fortunately. Not good enough to save our grandchildren from climate disaster, but at least a beginning, which we hopefully will be able to build upon. Apart from the climate change deniers, who live in their own claustrophobic world, much of the disagreement is about justice: which are the countries to blame, and which should clean up their acts first? The Paris summit tried to avoid the question of justice and convince us that we all have to contribute, including the developing countries. And the developing countries seem to have gruntingly accepted that.
