The White Man's Burden & Imperialism

Response to Kiplings "The White Man's Burden":
1. Determine what Kipling means by "the White Man's Burden"?
White man's burden, has actually been haded to some dictionaries as a noun. It's meaning was derived from Kipling's poem. According to dictionary.com it means, "the alleged duty of the white race to care for subject peoples of other races in its colonial possessions." He shows "the white man's burden" sort of as a responsibility of the "white" race to protect the other races, but not their own, for he writes, "Go, bind your sons to exile to serve your captives' needs."
2. Does Kipling justify imperialism? How so?
I think he sort does justify imperialism, for he shows it as one place helping another to have progress. Kipling describes it as a country putting others in front of its-self. Yet he shows another sort of view, too. His word choice displays how it is wrong and a sad, horrible thing to force people into a different culture. Kipling writes these things, "to veil the threat of horror," and "your new-caught sullen peoples," doesn't this paint a horrible fear in your mind? He writes with words of sadness, but his message seems to rejoice for progress is to come.
3. Why might such a justification might be so appealing?
It shows that even though the "captives" may see it as one way, it could be for the better. They new country might bring advancements and supplies. I guess what I am saying is that he shows how it could be taken as a kindly sort of gesture or one just to show great power and superiority.
