I don't see what's hypocritical about changing your mind some twenty-four years after making a decision when the entire context has changed and new evidence has come to light. He made a decision that made sense in 1995, he's since come to realise it no longer makes sense. Politicians that are capable of re-evaluating their position on things when presented with new findings is exactly what society needs. You shouldn't penalise them for not steadfastly holding to every opinion they've held or decision they've made.
