There's not a lot of point in arguing - the "projections" of the impact to the world are open to debate, and no matter what they won't impact during our lifetimes.

Thus, people either fall into a class of people who can believe there is, or at least accept their may be, a problem and want to do something about it, and those who believe (or hope) there won't, and won't behave differently. Since they don't believe, and have an argument to support it, changing the second type of person's mind is pretty much impossible (ie, they are hardly likely to see the error of their ways when it imposes such restrictions on them).

ronin - you have no idea. The rest of the world pretty much ranges from dissappointed with the US to virulently pissed off (as a nation state - you guys are great people!). The best you have right now is UK/Australia continuing to support.

We MIGHT all be wrong....
