"Curse Tullius for not giving Skyrim to the Stormcloaks! Well at least there is chaos in Skyrim. Now our Dominion soldiers will have to fight the Empire to take control of that area, if only we could have fought some solitary Nords with fantasys of beating the Aldmeri Dominion in one great battle. We here at the Dominion are just so glad that Nords can't think 10 years ahead. Let alone 50. Let alone 200 years. Thankfully we Altmer are gifted with a lifetime that lasts centuries. The humans pathetic fighting will make for good entertainment while we rebuild" - Random Thalmor Emmisary, Alinor 4E201 Exact Date Unknown =^ Tullius is actually awesome <3
For a person claiming the nords have no foresight, you ignore that Tulius gets every strategy wrong in the entire quest line up until the siege of Windhelm. It's the nord woman, Rikke, who makes all the right calls.
And by the way, Hammerfell repelled the Aldmeri dominion after the Empire sued for peace and disowned them. The empire didn't leave people behind that time, either.
Addendum: It's also worth noting that Elves fear Humans because Humans reproduce faster than they do. The Aldmeri dominion fought the Empire to a standstill. The Human population will rebound faster and then sack the Elves. In their greatest moment, the Elves failed to seal the deal and doomed themselves, much like their Snow Elf predecessors in Skyrim when Ysgrammor first settled.
