FDR's New Deal was successful at combating the Great Depression. After implementing his New Deal policies, the unemployment rate dropped by roughly 10% in the first few years. Along with this, the programs helped to build America's infrastructure, parks, and resulted in the creation of several long term agencies that exist today (like the SEC and FDIC).
The New Deal affected future generations by creating agencies that still exist today. A perfect example is the Social Security Administration. This gives financial assistance to America's elderly population. This system is one that most employees currently pay into. This has been seen as a successful program, as it helps to pay for several different things (like medical costs) that senior citizens would otherwise struggle to pay for.

The Battle of New Orleans was important because it was the last big battle of the War of 1812. American forced repelled the British army and won a decisive victory. This gave the US a good position during the Treaty sign and Britain had to lose some terms.
The Treaty of Versailles stated (to name a few) that Germany had to have a small army/navy/air force and couldn't try to expand their empire by taking over other countries, Hitler did this anyway, sparking WW2.
