Mr. Speaker, the United States has not taken a decision yet to deploy a national missile defence system and Canada has not been formally asked to participate in an NMD system by the U.S. Consequently, it is a completely hypothetical question. We cannot yet take a position. There are still too many unknowns.
I have to add that the U.S. has confirmed that the deployment of a national missile defence system would require a change to the existing anti-ballistic missile treaty of 1972. The U.S. is pursuing discussions with Russia on this matter.
