I have chose to use the following question:

1. "Although Americans perceived Manifest Destiny as a benevolent movement, it was in fact an aggressive imperialism pursued at the expense of others." Assess the validity of this statement with specific reference to American expansionism in the 1840's.

I have started my basically brainstorming but am looking for help to further develop my ideas.

P(olitical) - American Manifest Destiny Belief and the "Spread" of democracy.
E(conomic) -
R(eligious) - Manifest Destiny as the "Will of God"
S(ocial) - Anglo-Saxon Superiority to other races in social matters.
I(ntellectual) - ^^Angle Saxon intellect being superior to that of Blacks & Indians
A(rt) - Probably not going to use this.

Do any of you have any further ideas that can help me expand this out.

Any help would be appreciated, thanx.
