The key point is that the motivation to invade largely Christian and Jewish Spain was based on both the wealth from the initial conquest and the wealth generated by the jizayh tax on the population.
First of all, most colonists were from Britain. This connected links to the British, so the British could come into America when they wanted. King George the Third implemented many acts into our Nation which angered the colonists. The more acts the King placed on America, the more opposed the colonists got. Then there was the French-Indian War which killed plenty of our men because of how cocky the British were.

Answer:
The brief war fought against the Spanish Navy and land forces in 1898 established the United States as a global, major navy and military power.
The war was fought in Cuba - the Caribbean - and in the Pacific. If a century before American governments were not willing to join wars among European powers and pursued a cautious diplomacy, full industrialization, territorial expansion and a fantastic growth of economic might made the United States a player in world affairs to be reckoned with a century later. That´s why the Spanish-American war is a turning point in American history: the US would play a large role in world affairs from that moment on.
Off the top of my head:
The US devised the Manhattan project during ww2 and afterwards to develop nuclear weapons. The kept this secret from USSR even though they were allied. This contributed to Stalin’s paranoia and increased tensions between the two countries.
You also mention how Truman used this ‘atomic-monopoly’ to give him confidence and make him think that he could dictate decisions during the Potsdam conference and other meetings which heightened tensions with USSR.
Nuclear weapons also played a large role during the Cuban Missile Crisis, the point where nuclear war was at it’s closest to becoming reality and destroying the world.
By that point the USSR had also developed atomic bombs. The fact both superpowers had nuclear weapons meant they had to be sensitive in the way they handled each other and you could link this with Cuba and argue that it was the only reason the Cold War didn’t turn into full-scale, physical war.
There’s other things you could say beyond these points as well.
