What was the outlook of the war for the allies prior to D-Day?

by Jimbobmij

As the title says, prior to the successful Normandy landings, how likely did an allied victory in the war seem at that point?

Very, on a global scale. The Allies had taken Rome that same week, Italy was a divided state with rival governments fighting on both sides of the war, while the Mediterranean and Atlantic had been made far safer for Allied shipping by the heavy blooding of the U-Boat force thanks to new technology and tactics. In the air new bases in liberated Italy and Sicily allowed for a supplementing of the strategic bombing efforts into regions of Eastern Europe previously out of range, while German forces were badly depleted. Big Week in February had intentionally sought to use the new long range escorts like the P-51 to bleed Luftwaffe fighter forces attacking Allied bombers and did so to great success.

In the East, Soviet Russia was preparing for one of the largest land offensives of the war in Operation Bagration. This offensive launched in late June would practically annihilate Army Group Center and take Soviet Forces beyond even their pre war borders back into Eastern Poland firmly setting up the final death spiral of German fortunes in the East. Earlier in the year the siege of Lenningrad had also been lifted and the Soviets had made bloody advances elsewhere including the Crimea.

In the Pacific then the great confrontation that the Imperial Japanese Navy had sought was about to be upon them. Allied forces had taken the outer defensive rings of the GIlbert and Marshall Islands and continued to advance in New Guinea and the Solomons. Before them lay the key Marianas Islands, the battles of Peleliu, Saipan, and Guam would all go down as brutal examples of island fighting. But the rebuilt carrier force would would sorties in response to the US landings in late June on Saipan, where they would be annihilated at the Battle of the Philippine Sea. While in East Asia the Japanese Army and British fought in Burma and India, at great cost a Japanese offensive was pushed back and the Allies woudl begin the drive to liberate occupied SE Asia. While Allied submarines continued to strangle the needed sea lanes leading to Japan.

1944 was the year much of the overwhelming structural, economic, and organizational powers of the Allies began to show. And on the ground much of it was already obvious. There was not a theater where the Axis had not at least been checked, or thrown into full retreat and the pressure only increased as the year went on. Much blood and destruction remained to be extracted on all sides, but the tidal wave of the United Nations was reaching its crest.
