Document D: Henry Wallace

Read the following passage and answer the following questions 

I have been increasingly disturbed about the trend of international affairs
since the end of the war.
How do American actions appear to other nations? I mean actions [like] the
Bikini tests of the atomic bomb and continued production of bombs, the
plan to arm Latin America with our weapons, and the effort to secure air
bases spread over half the globe from which the other half of the globe can
be bombed. I cannot but feel that these actions must make it look to the
rest of the world as if we were only paying lip service to peace at the
conference table.
These facts rather make it appear either (1) that we are preparing
ourselves to win the war which we regard as inevitable or (2) that we are
trying to build up a predominance [largest amount] of force to intimidate the
rest of mankind.
Our interest in establishing democracy in Eastern Europe, where
democracy by and large has never existed, seems to [the Soviets] an
attempt to reestablish the encirclement of unfriendly neighbors which might
serve as a springboard of still another effort to destroy [them].
