Avalon1,
I'm surprised there weren't more either, especially when you remember that the 101st was deployed in-country from Diego Garcia and after violating the airspace of Kenya, Tanzania, and Burundi. Given the immediate nature of the crisis, there simply wasn't time to complete negotiations with those countries regarding access or even logistical basing thus forcing Bush's hand.
While the President did cover his bets by using a carrier airwing to cover the 101st's transport aircraft, the sight of US warplanes shutting uninvited across the skies of Kenya and Tanzania damaged relations with those tow nations and is felt by many to have led to the embassy bombings later in the decade.
Even after securing the airport at Kigali, the 101st was operating under logistical constraints not seen since Bastogne n 1944. The resulting supply effort caused the USAF to call up reserve pilots and aircraft, something not seen since the Gulf War, and to detriment of US commercial carriers. Despite having it's recent Gulf War experiences to call upon, the USAF performed rather poorly sparking several Pentagon inquiries and raising questions again about the force's commitment to joint warfare.
On the other hand, the Marines and 101st got along splendidly. After Tanzania allowed US overflights, thanks to millions in bribes in the form of "aid", and a marine expeditionary force with the much needed helicopters arrived, the intervention was able to begin patrols much further away from Kigali. Sadly, the 48 hours this took was enough for a huge number of deaths to take place.
All in all, the US intervention was a marvel. Many are still amazed that it could have occurred at all, especially given the fast moving nature of the crisis and the awesome logistical challenges involved.

P.S. In reality, no military force could have intervened in Rwanda in any appreciable manner. The crisis occurred too quickly and the region is too remote. Logistic concerns trump everything. That's why military professionals, as opposed to bleeding heart, armchair quarterback, amateurs, study logistics above all.
