You are certainly entitled to that opinion. And over time you just might get your wish.

Wouldn't this involve the use of a time-travel device?
Unless there is a change in the space-time continuum, having invaded Iraq, we shall ALWAYS have invaded Iraq.

I mean, unless time travel is effectuated, I mean.
