Reaffirming but he's putting some context, Achdus? Yes, but not at any price.
So now, the big question is how motivated is the TOP to achieve achdus. If all this means that we can unite as long as I get to dictate the rules, then I'm afraid this might be nothing new. If, on the other hand, there's a true motivation for achdus, which means that there can be legitimate disagreement, and acknowledgement that while I might find my way to be the true way, I can find validity and accept another way, then we might make serious progress. This requires true גדלות המוחין.
An example I often bring to this is the attitude towards entering the Rebbe's room. Some people feel that their hiskashrus to the Rebbe leads them to want to be there as much as possible, while others feel that their hiskashrus to the Rebbe prohibits them from entering the Rebbe's room. Being able to feel a strong conviction one way AND ACCEPT AND RESPECT THE OTHER WAY AS TRULY VALID is where we should be.
