Why was Stalin begging the Allies to open a second front in Europe in 1942-1943?

Explanation:

Throughout the war, the USSR was supplied by its allies in the British Empire and the US. Food, weapons, aircraft and many other types of supplies were sent by air and by sea on incredibly dangerous journeys. Although he appreciated this support, the Soviet leader Josef Stalin constantly pressured his allies to start a Second Front in the war which would relieve pressure on his forces in the east.
