The Allies had enough troops and supplies later in the war that made sense to attack everywhere to force Germany to commit troops. The Germans had 27 divisions in Italy in 1944. The Allies could have been more aggressive like not letting German forces escape at Anzio. But could have been less aggressive in attacking defensive lines wasting troops for slow advance. Also, the 15th Air Force operating from Italy brought lots of Eastern Europe in range of bombers.
