Allies would have won WW2 without America.

No. The more they're, the more are the chances of their victory. If USA hadn't intervened, the Allies would surely have been defeated.The U.S supplied Great Britain, the USSR, Republic of China, Free France, and others Allied nations with materiel between 1940 and August 1945. A total of $50.1 billion (equivalent to $650 billion today) worth of supplies were shipped. That represented 17% of the total war expenditures of the U.S. In all, $31.4 billion went to Britain, $11.3 billion to the Soviet Union, $3.2 billion to France, $1.6 billion to China, and smaller sums to other Allies. The U.S Industry produced over 2,382,311 military vehicles. 102,410 Tanks and Self - propelled guns 99,950 Fighter Aircraft 97,810 Light and medium bombers 35,366 Four-engined bombers 257,390 Artillery (including Anti-tank and anti-aircraft guns) 105,054 Infantry weapons: Mortars 2,679,840 Infantry weapons: Machine-guns (without sub-machine guns) 11,750,000 Infantry weapons: rifles 1,956,000 Infantry weapons: sub-machine guns 3,918 Reconnaissance planes 141 Aircraft carriers 8 Battleships 48 Cruisers 349 Destroyers 498 Escorts (Corvettes, Frigates) 203 Submarines The 1940 Destroyers for Bases Agreement, whereby 50 US Navy destroyers were transferred to the Royal Navy and the Royal Canadian Navy in exchange for basing rights in the Caribbean. The USSR received hundreds of thousands of military vehicles and motorbikes. Lack of fuel was ameliorated with deliveries of 2.5 million tons of petroleum products. The profusion of Roosevelt's "garden hose" provided Stalin with 595 ships, including 28 frigates, 105 submarines, 77 trawlers, 22 torpedo boats, 140 anti-submarine vessels and others. The Soviet air force received 4,952 Aerocobra and 2,410 Kingcobra fighter jets. Soviet pilot Alexander Pokryshkin fought with Hitler's Luftwaffe aces in Aerocobra planes, which made him a Hero of the Soviet Union hero three times over. The lend-lease agreement supplied the USSR with 2,7 thousand A-20 and 861 B-25 bomber planes. Soviet tank divisions received 7,056 tanks, 8,218 anti-aircraft emplacements, 131,600 machine guns and other arms. The USA provided the Soviets with 501,660 tactical wheeled and tracked vehicles, including 77,972 jeeps, 151,053 1-1/2-ton trucks, and 200,622 2-1/2-ton trucks. Soviet propaganda tried to diminish the importance of the American help. Back in those years, it was said that the Soviet Union had produced 30,000 tanks and 40,000 planes since the middle of 1943. Well, as a matter of fact, this was true. However, one has to take into consideration the fact that lend and lease deliveries were made to the USSR during the most difficult period of the war - during the second half of 1942. In addition, the USSR would not have been capable of producing its arms without the lend-lease agreement: The USA shipped 2.3 million tons of steel to the USSR during the WWII years. That volume of steel was enough for the production of 70,000 T-34 tanks. Aluminum was received in the volume of 229,000 tons, which helped the Soviet aviation and tank industries to run for two years. One has to mention food deliveries as well: 3.8 million tons of tinned pork, sausages, butter, chocolate, egg powder and so on. The lend-lease agreement provided orderlies with 423,000 telephones and tens of thousands of wireless stations. Deliveries also included oil distillation equipment, field bakeries, tents, parachutes, and so on and so forth. The Soviet Union also received 15 million pairs of army boots. The help was delivered to the USSR via Iran and major Soviet sea ports. About 3,000 transport vessels arrived at the ports of Murmansk, Arkhangelsk and Vladivostok, and delivered 1.3 million tons of cargo. It would be incorrect to diminish the significance of such all-embracing help from the United States as a serious factor that assisted in the victorious ending of the war. The Soviet Union had also pressed the United States and United Kingdom to start operations in Europe and open a second front to reduce the pressure of German forces on the Soviet troops The U.S favored Operation Sledgehammer, landing in Occupied Europe as soon as possible, but the British commanders believed that such a course would end in disaster. So an attack on French North Africa was proposed instead, which would clear the Axis powers from North Africa and improve naval control of the Mediterranean Sea, and prepare for an invasion of Southern Europe in 1943.
