That is an excellent question. The immediate theory that leaps to my mind is that "official knowledge" by the Reno Justice Dept. of the Iraq connection would have required Clinton to wage war against those responsible. Possibly this would have meant bombings and assassinations of terrorists, and an invasion of Iraq proper with the ousting of Saddam Hussein.
All this would have meant the end of Clinton's peace initiatives in the Middle East, and thus the end of any chance of Bill Clinton being remembered as the Great Peacemaker that brought Arab and Jew together at the table of brotherhood.
All of this sounds laughable to you and me, but remember the arrogance of Clinton knows no bounds. Clinton wanted desperately to be remembered as the man who brought peace in our time. He was willing to go to any lengths necessary to get it. The above is only a theory, but I believe a plausible one.
Glad to see that I'm not the only one who has thought of this, Zack.
