At this point I'm not sure why they're even bothering (and for the record I am Jewish, and if I were Harry Truman, I would deliberately extended the war against Germany to use the atomic bomb against them, they deserved it- but now they've more than paid their pennance)
As it was, the Americans had stopped pushing towards Berlin. Uncle Joe Stalin wanted dips on Berlin and he got it. Truman had no say in the matter of determing how long the War lasted, that was all dependent on how long it took the Red Army to steamroll Berlin by March/April/May 1945. Not driving into Bavaria and Austria, would have merely given the Soviets a bigger piece of Germany as well as all of Austria to "liberate", which could have meant a larger East Germany and a Communist Austria during the Cold War.
