I’ve figured it out.

The fleet will travel back in time and return to Earth, pre-nuclear war. Their arrival will change history and prevent the war; instead, they’ll all go to a concert and hear Bob Dylan sing the definitive version of “All Along The Watchtower”.

And everyone will live happily ever after.

Remember, you read it here first.

“Free Bush”

By Jeff Singer, with apologies to Lynyrd Skynyrd

When I leave here tomorrow
Will you still remember me?
For I must be travelling on, now,
‘Cause there’s too many places I’ve got to invade.
But, if I stayed here with you, Congress,
Things just couldn’t be the same.
‘Cause I’m as free as the Surge now,
And this surge you can not change.
Lord knows, Iraq can’t change.

Bye, bye, its been a sweet term.
Though this country I can’t change.
But please don’t take it badly,
‘Cause Lord knows Katrina’s to blame.
But, if I stayed here with you America,
Things just couldn’t be the same.
Cause I’m as free as my legacy now,
And this legacy you’ll never change.
And this legacy you can not change.
Lord knows, I won’t change.
Lord help me, I won’t change.
