Thank you, Mr. Chair, and to both of the witnesses.
Dr. Ramana, the world is deeply concerned about nuclear weapons right now, given Putin's war against Ukraine. Canada is standing in solidarity with the people of Ukraine as they stand up to Putin's aggression. It's been extremely troubling to see him threatening the world with the use of nuclear warfare.
You mentioned in your opening remarks the risk of nuclear proliferation. Can you speak a bit more about that danger?
