"Maybe some international cooperation right off the bat would've lessened the BP impact."
Maybe early on with the spill response, but even that's doubtful from what I've read. Nobody had a way to deal with that for the whole problem, and they probably won't next time either. To me if there's ever a next time, the emphasis will have to be on stopping the well, rather than a better response to cleaning up the mess. Look at how fast things were under control, relatively speaking, when they stopped the leak.
As far as stopping the well, I think they had the best in the world available from the get go. The equipment used to stop the well took some time to build, and the support vessels to deploy it were there early on. The stuff they did subsea before that was just shots in the dark hoping to do as well as they could. The way they do better next time is to have some of this existing when it happens and that's already underway.
Hats off to the Chile government and whoever else involved for allowing and encouraging the help and resources needed to get those guys out.
Some days we don't get to hear about all the great people in this world and the good things they do and can make happen. Yesterday we got to hear about them and see them and that was great.
