Dude would have been a great president, and having him at the helm instead of Bush would have drastically change global politics to this very day.
People keep saying that and they keep being wrong.
There was no daylight between Bush and Gore on foreign policy, and very little daylight between Bush and Gore on domestic policy.
A hypothetical Gore administration would have invaded Afghanistan. It would have invaded Iraq. It would have implemented the Patriot Act and instituted the policy of destabilizing Muslim countries to honeypot terrorist groups into civil war (the so-called "Bush Doctrine"), all the vicious realpolitik warmongering that Kissenger taught Clinton and Bush and Obama to do so well.
Understand: we have lived under the Kissinger Administration from 1972 to the present day. Anybody who thinks a different President would have made a difference in global politics is fooling themselves.
