Plus, in the words of Yoda, war does not make one great. But the president in your story is basically praying for a war so he can reap the glory - sounds like he would be better up joining forces with the Empire than the rebels.
Lando gives in a bit easily doesn't he? There's nothing to suggest the hyperspace mistake was his fault, and he definitely hasn'r 'betrayed' the alliance. Let them down maybe, but not betrayed. By the time of the attack on the death star II Lando has matured and developed. I think Lando would be the only one keeping a cool head and trying to think of a way out of this mess. He's been in tight spots before, this is just one more.
Sorry for the criticism, but I hope it is at least constructive criticism. As for the bits I didn't criticize - Good job.
