Thank you for the questions.
I would say that conditions for nuclear disarmament are very poor. As you know, there are concerns of the Russians walking away from the INF accord of 1987. The North Korea situation is very visible. It's a very big concern.
After the very successful round of negotiations and the result of New START, the political relationship between the United States and Russia has deteriorated a great deal.
I would be highly concerned to put Canadian political capital in the middle of that very difficult environment and I would say we are far better off to wait for the right conditions or to specialize in an area where we can make a genuine difference.
