No, there would be more conflict, more fighting, and more bloodshed. Also, the Horde is fractured and in need of some rebuilding once Garrosh is dead, but how long do you think it would take them to reunite if the Alliance became "the enemy" and "an immediate threat" immediately following the siege. The Horde will not feel like they "owe" the Alliance anything just because they killed a common enemy together, so any attempt on the Alliance part to conquer or take back any land would be met with conflict, not negotiations. I think Varian just understands this, and decides to get while the getting is good, and escape with the military advantage that they gain from killing the Warchief of the Horde. I'm sure many lives, both Alliance and Horde will have been lost by the time Garrosh Hellscream falls, and I think also an attempt to crush the remainder of the Horde with a tired and depleted group would be a much more difficult task anyways. They'll live to fight another day for the lands they want back. After all, there are more expansion, hence much more opportunities to fight the horde over this land.
