Why did daisy try to get tom calmed down in chapter 7?

During the encounter between Tom and Gatsby at the Plaza hotel, Daisy crumbles rapidly, backpedaling on her assertions of loving Gatsby and never having loved Tom. She says to Gatsby

"Oh, you want too much! I can't say I never loved Tom. It wouldn't be true"

Tom quickly capitalized on Daisy's wavering loyalties to reassert his control over her. He tells Gatsby that "there's things between me and Daisy that you'll never know, things neither of us will ever forget." He also goes aggressively after Gatsby's shady past and the insecure foundation his wealth is built on, knowing full well how much money matters to his wife.  Daisy most likely realizes that she is a fantasy figure to Gatsby, a representative of his desire for lost youth, wealth, and security and that his needs are insatiable and unrealistic. Her relationship with Tom may be troubled, but, as he reminds her, it's real and rooted in a shared past.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
