I don't know about the Canadian officers.
One of the things that has changed the threat environment is the unexpected rate of progress in North Korea, where they seem to have acquired probably some Russian design work that has really enabled them to make huge progress with missile engine technology. We've now seen them make enormous strides incredibly rapidly to enhance the range and capabilities of those systems. Whereas we once had the luxury of geography—and as Jim explained, the European-based system can't do very much or have any effect on stuff coming from Europe to here—we now need to start looking at the much more immediate threat .With current technology, the only way is to put stuff that can address the terminal phase—for which the European system is very useful in Europe, but actually useless for North America. The threat environment has changed. It's added much more urgency to your considerations.
