President elect Obama's Ambassador-designate to the UN  Susan Rice was a major roadblock to capturing Osama Bin Laden when the terrorist was operating out of Sudan in the 1990's according to anti-terrorism sources.

Evidently, Rice thought that accepting the offer of assistance from the Sudanese government to bring Bin Laden in was less important than trying to destroy them:

Terrorism experts blame Rice for having played a key role in blocking efforts to neutralize Osama bin Laden in the 1990s. According to Mansoor Ijaz, a former trouble shooter for Clinton, the FBI had their efforts to capture bin Laden "overruled every single time by the State Department, by Susan Rice and her cronies, who were hell-bent on destroying the Sudan."

In a Washington Post Op-Ed published in 2002, Mansoor Ijaz and Tim Carney, U.S. Ambassador to Sudan blamed Susan Rice for being a major obstacle to accepting offers of help from Sudan and to share their intelligence on bin Laden's terror network.

Rice was also influential in the Clinton Administration's remaining uninvolved in the Rwandan genocide that took place in that nation in 1994.
