The United States feared that if communism was successful on Vietnam, the rest of the countries that border it would soon turn into communism and those other countries that border that new communist country would also be converted to communism and so on. This is called the "domino theory" and made the United States to send troops to prevent the theory from happening.
Answer:
The Battle of Gettysburg, fought between June 1 and 3, 1863 between Union forces and Confederate forces, was one of the major turning points of the Civil War, as the Union victory stopped the Confederate advance in the territory of the north and left free way for the Union to be able to advance towards the territory of the south.
The battle itself was a massacre, with more than 50,000 dead in total. But in addition to being a military disaster for the Confederacy, it also had implications from a strategic point of view. An eventual southern victory would have implied a clear advance towards New York, which would imply an almost certain victory for the Confederacion. Furthermore, a Confederate victory would have encouraged France and Great Britain to ally with it to defeat the Union, which in those years was a major commercial adversary. Therefore, the victory of the Union in this battle prevented the participation of France and Great Britain in the conflict.
I would say appeal based on logic. I'm not entirely sure, but that's what makes the most sense to me :)
