I can't find the exact quote, but he says he says the Empire believes the Thalmor are planning an attack and that the Empire is preparing itself for a Second Great War.

I thought it might be the plot of a DLC, but since there's no more, we're going to have to wait 5-6 years for the Elder Scrolls VI.
