A123 sale to Chinese firm gets US approval

I think it's unfortunate that much in the way of technology and infrastructure to manufacture products from that technology, is being treated as something we can assume we'll always have access to in the future. The fact is that just because the world is a place today where there are sufficient incentives for products made in one jurisdiction to be available in another does not mean it will always be the case. Indeed this has not been the case for most of human history.

There are many reasons a fair-minded person could accept as plausible for believing that the coming decades could see a rise in conflict in the world rather than a continuation of trends towards more international co-operation. Some might argue this has process has already begun. Peaking of resource availability including energy resources; impacts of climate change.

In a world of increased conflict having strategic competitors controlling the only realistic and timely access to technology and production is indeed a matter of national security, and a risk which we are likely to regret not taking seriously at some point in the future, IMHO.
