As per mod instruction, creating a new thread for it.
The DUP wouldn't argue about an Irish taoiseach making an official speech like that?




The GFA is an agreement with the British 'parliament' the government of the day cannot amend it without breaking it. You do understand this?
Link to what he said and where he said it:

Again, you are talking about two different things and conflating them. The GFA was passed by both parliiaments. The very fact that it had to, proves that parliament has the final say in any such agreement being ratified.
In the GFA is the following arrticle:
(iv) affirm that if, in the future, the people of the island of Ireland exercise their right of self-determination on the basis set out in sections (i) and (ii) above to bring about a united Ireland, it will be a binding obligation on both Governments to introduce and support in their respective Parliaments legislation to give effect to that wish;
Again, this obliges the government of the day to introduce and support legislation to give effect to the plebiscite. It does not oblige the parliament of the day to pass that legislation. No more than parliaments of the past could oblige future parliaments to continue denying universal suffrage.
