[Quotation from Chief Justice Marshall] in American Ins. Co. v. 356 Bales of Cotton (1828): 
"The Constitution confers absolutely on the government of the Union the powers of making war and of 
making treaties; consequently, that government possesses the power of acquiring territory, either 
by conquest or by treaty."
