Because American troops were present in the disputed Neuches Strip.
The Mexicans attacked the Americans first in the Mexican-American War of 1846 primarily due to ongoing tensions over territorial disputes, particularly regarding Texas. The U.S. annexation of Texas in 1845, which Mexico still considered part of its territory, escalated these tensions. When American troops, led by General Zachary Taylor, were stationed near the disputed border, Mexican forces saw this as a provocation and launched an attack, marking the beginning of the conflict. This clash was fueled by broader issues of expansionism and manifest destiny in the United States.
It was first introduced in 1846.
The Battle of Palo Alto was fought on 8 May 1846.The first battle was the Thornton Affair on 25 and 26 April 1846.
The ill-defined border between Texas and Mexico allowed for this type of confusion: while Mexicans believed the Rio Nueces to be the border between both countries, the Americans thought the Rio Grande was the actual border. This led to skirmishes, and eventually escalated into the Mexican-American War (1846-1848).
Manifest destiny was a flawed theoretical justification for U.S. expansion an taking over of territory that was not theirs, Same as Abraham's Lincoln's: Lincoln made a speech on the House floor in which he pointed out that the Mexicans had made no hostile acts toward the United States and had been attacked in an area which was rightfully theirs

That was the U.S.-Mexican War. It was from 1846 to1848. The war between the United States and Mexico had two basic causes. First, the desire of the U.S. to expand across the North American continent to the Pacific Ocean caused conflict with all of its neighbors; from the British in Canada and Oregon to the Mexicans in the southwest and, of course, with the Native Americans.
Mexico severed diplomatic ties to the United States after the U.S. annexed Texas, and started a low-intensity conflict along the US-Mexico border, which actually, was ill defined -- Americans believed the border to be the Rio Grande River, while Mexicans thought it was the Nueces River, several miles to the north.This resulted in skirmishes between Mexicans and Americans, resulting in American blood spilled in this no man's land. This was used by president Polk as a casus belli to start the war. He however, was uninterested in Texas: he wanted to "acquire" California from Mexico at any cost.
It was first introduced in 1846.
The main disagreement between the United States and Mexico in 1846, when the war began, was the boundary of Texas. The state was just annexed to the chagrin of the Mexicans, who had lost it in 1836 to independence. Mexico had the boundary at the Nueces River, but the Americans believed Texas should stop at the Rio Grande, to the south. In 1846, President James Knox Polk ordered General Zachary Taylor into the disputed territory between the two rivers, and the Mexicans crossed over to engage them. This gave Polk the excuse he needed to ask Congress for a declaration of war.
Yes; The British intercepted a telegram sent from Germany to Mexico asking the Mexicans to attack the U.S. if the U.S. got involved in WWI. They promised the Mexicans money and a return of AZ, CA, NM territory lost by the Mexicans to the U.S. in the Mexican American War of 1846-8. Mexico considered it, after all, they did not like the U.S. or Wilson, but were more afraid of the U.S. than Germany. Plus, Germany is 1000s of miles away... it was one of the factors that helped bring us into the war.
