Question

What reassured Europeans that the u.s. would help them rebuild their lives even in the shadows of growing Soviet hostility?

Answer 1

There were two things that reassured Europeans that the United States would help them rebuild their lives even in the shadow of growing soviet hostility: the Marshall Plan and the Truman Doctrine. 

Answer 2

The correct answer is the airlift to supplies to Berlin.

The airlift to supplies to Berlin reassured Europeans that the United States would help them rebuild their lives even in the shadows of growing Soviet hostility.

When Joseph Stalin ordered Soviet troops to blockade all the entrances and exits to and from Berlin, Germany, he tried to make sure the United States supplies would never get to Berlin to help its citizens. But the United States considered another valid option, although more costly, by air. SO yes, the airlift to supplies to Berlin reassured Europeans that the United States would help them rebuild their lives even in the shadows of growing Soviet hostility.
