True, but in our (I think, though I'm probably wrong) 1 PoV from Rand in ToM, we don't know that he means to break the seals WHEN he says he will, or what his justification is. We know he has nit finished his plan, but that is it- not that he has no plan. It's pretty easy for a good writer to hide stuff in a PoV without making it obvious, and we havent had a lot of Rand Pov's in recent books. We know he still has an answer from the 'Finns that we know nothing else about from books ago. Just like how his other answers led him to formulate a plan to cleanse Saidin that we didn't find out about for ages. Which worked. And needed final details near the end. Just like this.

We know he claims to have an idea of how to KILL the DO. He is one with LTT now. He has admitted in the same paragraph that you refer to that he got Egwene to bring the leaders of the world together to hear his demands. Please don't assume Sanderson and Rand have given you all the facts, because in earlier similar situations in the books even when we had more Rand PoVs and he was less devious, this is plainly not the case. Needing to fill in the details is not the same as having no plan, and we have had less of a Rand PoV for a reason. We saw a lot of Rand Through other characters but I checked and the epilogue, which was tiny, was Rand's only PoV in that book. That's pretty much no direct data to make assumptions on, and all we know is that Rand is sure he needs to break the seals and has said he will do so after (but not necessarily straight after) this meeting. Anything else by you or me is inference. And other characters have said he will need to clear the rubble before trapping the DO again, it makes sense in RL logic and characters like Elayne and Nynaeve who were told of his plan by Egwene thought it was reasonable until she tried to change their minds (not by producing a better idea or trying to analyse why to do it or why not or arguing that plans need to be put in place first, but by insisting that it was illogical and mad without making a real argument that we can see in her many extensive PoVs). So whilst I agree that the argument is artificial, that's not artificial from the author but artificial from Rand and from egwene's predictable reaction. Which means in literary terms it is real. I agree that another argument about the Seanchan will overrule it unless the battle of caemlyn stops the meeting from happening anyway. But I strongly disagree with the assumption that there is no plan after breaking the seals, or that Rand's logic that it's best to act on his terms and not wait for his forces to fall apart (which they will when Caemlyn is attacked and te Black Tower betrayal comes to full fruition) than wait for ever for a plan that might never come, won't be perfect and the greatest minds of the age of Legends couldn't get to work.
