I would say to you that Mr. Putin thinks he has found an answer to article 5 of the NATO treaty, according to which an attack on one of the NATO countries is an attack on all of the NATO countries, and that he is using the threat of nuclear weapons to intimidate the NATO countries.
We are faced with a choice: either we allow Mr. Putin to threaten us, to lead us around by the nose, to violate just about every international treaty, and to say that he will use chemical weapons or nuclear weapons, leaving us at his mercy, or we take the necessary steps to end this genocidal war and ensure stability in Europe, which necessarily includes respecting the borders of Ukraine.
