【明報專訊】''When two opposite points of view are expressed with equal force, the truth does not necessarily lie midway between them. It is possible for one side to be simply wrong,'' quotes Richard Dawkins in his famous work The God Delusion. Russia's invasion of Ukraine is a case in point. Any justification of the invasion, such as NATO's repeated eastern enlargement, does not survive the least rigorous scrutiny. To say that NATO, a defence alliance, poses a threat to the security of another nation is to say that the existence of a fire station poses a security threat to an arsonist.
