We would be delightful and ask to buy your land .

The America uses many ways to get the land, for exp: Buying it or maybe some time lead to a fighting war or be delight signing treaty or be arrgesive and have a argument
Even Though taking other people country is not a right thing but the America had did a good job on helping the place being better and educates more people so they can fight back with their head so other people can't make them be slave and have a good job . Because of that the U.S.A have been upgrade and have more new technology
Because America is a strong country so they wanted to expend it out . Since their ;and is so big now so they seperated into 2 side South and North . And because of the slavery from the South .
Meanwhile the Manifest is happening the North(Abraham Lincon) declare the war on the South to solve the problems happening in both sides .
