Why did it take so long for the world to respond to the atrocities of the Holocaust?

Many did not want to believe, for others; they were already war-weary and they paid little attention to yet more suffering.

Explanation:

America was one of the many countries who, in the beginning, didn't do much for the Jews in the Holocaust. They didn't even let the Jews come in because they didn't want to be a part of it.

depends on the age of the teen, many believe by the age of 16 a person should know the strong difference between right and wrong along with the difference between risky and immediate death. swimming with sharks might be dangerous but swimming with sharks while bloody meat is attached to you is just insane. even more if you have no idea what you're doing. however, no matter the age, as long as the person is skilled enough and has the mental and physical capacity to control their actions doing whatever sport they put their mind to is all that matters.
