LAD #12 - Polk's War Message

In his address, Polk asserts his reasons for entering war with Mexico. He begins by noting that in recent years America's diplomatic relations with Mexico became strained because of disputes over land claims. He continues by noting that the United States tried to maintain "honorable terms" by sending a negotiator James Slidell to speak with the head of the Mexican government, General Herrera. Unfortunately, the Mexicans were not in a position to negotiate. Throughout the 1840's, Mexico underwent several revolution, and the political system was constantly changing. The negotiations would also cause a revolution because the Mexicans were disgusted by Herrara decision to allow an American to enter their country. As a result,  Herrara lost his position of power and the Mexicans decided to stop the negotiations. The Mexicans instead worsened their diplomatic relations by attacking American troops near the Nueces River in Texas (which was unnacceptable because the 1836 Treaties of Velasco made the area officially American territory). This would grow further out of porportion as future Mexican attacks would lead to the deaths of American troops. Because of this, Polk asserts, America had enough reason to enter war.
