There exists the same question that has the following choices.

A. They started the Cold War between the U.S. and the USSR.
B. They led directly to war on the Korean peninsula.
C. They codified international humanitarian law.
D. They divided Germany into eastern and western parts

The combined effect of both the UN Universal Declaration of Human Rights and the Nuremberg Trials is that A. They started the Cold War between the U.S. and the USSR.

I’d say either a or d i’m sorry if it’s incorrect.
