Without a successful operation, the allies may not have been able to get all the necessary supplies and troops into Mainland Europe.
Germany was able to fight a 2-front war in Western and Eastern Europe.
Russia wanted the other Allies to invade Europe and put pressure on the Axis from another direction. This would mean that Germany would have to divide their forces as well as supplies.

Stalin wanted the Allies to open a second front in Europe to releive pressure from his advancing army. If a second front was opened Hitler would have to split his forces and deal with two prongs that were advancing on Berlin and the Rhine, or the production heart of Germany. If either of these were taken Hitler would lose the war. The second front was made to put more pressure on Hitler and end the war quicker.
In World War II, the greatest problem for the Allies in establishing a second front in Europe was the shortage of landing craft. To be successful, amphibious landings on defended shores required large first waves of attackers supported by vehicles followed up by substantial reinforcements, including more vehicles. All this required landing craft in such numbers as the Allies weren't able to muster until 1944.
