LAD 12

The US and Mexico were in need of diplomacy to achieve peace between nations, so the US sent Slidell, a minister, to conduct negotiations on the boarders and tensions between the US and Mexico, and he was assured by General Herrera, that the mexican government would except him. However, when he arrived a revolutionary party forced the government to reject his request to negotiate terms with the US. Soon after this General Herrera had to surrender his power of mexico after a military take over of Mexico, and Paredes took power. This government was even less open to commence negotiations, and eventually lead to further disputes and conflicts along the Texas Mexico boarder. This resulted in a build up of troops on both sides, and Mexico declaring war on the US as a result of the troop build up creating conflicts. President polk said that the US should carry out the war to protect American interests and honor, in his speech to the American people.
