Why did world war i seem like an ineffective effort to many americans? how did this affect americans' views of war?

Because they saw the conflict as a European war, with interests and ideas that did not match with the Americans. The efforts to send men to fight in a war that, according to many Americans, it was useless, it was a waste of time and money. Even with the bombarding and sinking of the Lusitania in 1917, and the constant patrolling of German submarines in the Atlantic Ocean, the majority of American citizens didn't see a need for this war. They bought the war, as we know. However, after the conflict, the point of view about the conflict, and the reasons to start one changed enormously, and the isolationist politics returned with strength.
