I suppose a good tongue in cheek response to this question would be that the Soviet Empire died, making the leader of the sole superpower on the planet. While this is technically not the same thing as being God, it's pretty damn close.
He isn't the President of Zimbabwe, and the Zims need to take control of their own destiny.
No, that would be Robert Mugabe, and technically, you might say the "Zims" have done that. The "opposition" in Rhodesia/Zimbabwe is about as effective as the opposition in Iraq right now, and ZANU is running roughshod over them.
Afterall, the US military can't be expected to take care of every tinpot dictator, there's just too many of them and their own people need to do something.
Oh, I agree with you to some degree on this. But I'm not suggesting we go it alone. Another poster made some very good suggestions on how the British might play into this.
The point that I am making is that the opposition in Zimbabwe stands no chance of liberating their country without outside support. And GWB is, although not God, the leader of the Free World. I can't think of anybody more appropriate to play a leadership role in addressing that fact. And from what I've seen about GWB, putting the whack on "tin-pot dictators" seems to be something he shows a natural talent for.
