There is no doubt that all the great powers, especially the five permanent members of the UN Security Council, will oppose any move for global tracking of flights. They have had a long track record of weakening, rather than strengthening, global multilateral institutions. They have even weakened multilateral institutions like the World Health Organization and the International Atomic Energy Agency, even though we have a global interest in strengthening them to prevent pandemics like Ebola and nuclear proliferation.
Generally I approach accidents like a surgeon to her patients. Cool detachment. "Minor" incidents are a piece of cake. They are proof of our procedures working, every day. The major incidents are like old relationships -- you feel differently about each one. And for some reason, the missing Malaysian Airlines jet sticks out.
