I suppose you mean the Vietnam War, Korean War and both World Wars since you chose those types of categories. I will give you answer for each one.
World War 1: Some of our ships were sunk by the Germans. Political leaders of the US also chose to declare war on Germany for many reasons that were really rather dumb and senseless. (no time to get into it all, that entire war was senseless and accomplished nothing)
World War 2: President Roosevelt wanted to help the Brits with their dilemma in World War 2 but the Americans did not. Japan attacked the US and then the Americans wanted to fight. Adolph Hitler declared war on the US. Hence they were involved whether the American people wanted it or not.
Korean War was a war of the Cold War. The Koreans asked the US (and I think the United Nations for help). Initially they went over to help them but did not send thousands of troops or very well trained troops. The war escalated so the US became involved in the war.
Vietnam War: The US was requested by the South Vietnamese Government to come help them with war consultants and later troops to teach and help. Later the war escalated and the micromanaging Presidents and War Cabinets sent in hundreds of thousand of troops and drafted men into that war.
America is not involved in all wars but they are involved in most of the United Nation dilemmas in which troops are sent to some place in the world. They did start the war against the Afghans and the Iraqis that were considered part of the 9/11/2001 attack on the Twin Towers.
World War I - because it brought in the whole of the British and German Empires, and involved conflicts in Africa, South America etc.
Comparing it with Central American countries, yes! Nicaragua has the largest and best equipped military force of Central America. Worldwide, not too strong.
America is not in any way involved in the Gaza Strip Crisis. The only tangential involvement is that America supports the State of Israel and trades military hardware with them. The United States was diplomatically, militarily, and economically absent from the Gaza Strip and Operation Cast Lead.
America and American troops were not involved in the basically maritime-only Russo-Japanese War, however American President Theodore Roosevelt was awarded the Nobel Peace Prize for mediating the end of the war between the two belligerents.
The United States of America currently has conflicts with the countries of Iran and Syria. The U.S. also has a tense relationship with Cuba.

America did not want to be involved in distant conflicts. But when Germany sunk the Lucitania, America had no choice they had to enter.
US Civil War and Indian Wars (Frontier Wars).
No, not in any military sense anyway.
Comparing it with Central American countries, yes! Nicaragua has the largest and best equipped military force of Central America. Worldwide, not too strong.
The rivalry among England, France, and Spain in North America mirrored their broader global conflicts for dominance, particularly during the 17th and 18th centuries. Each nation sought to expand its territorial claims, secure valuable resources, and establish trade routes, which were vital for economic and military strength. The competition often led to conflicts such as the French and Indian War, which not only impacted North America but also had significant repercussions in Europe and other regions, highlighting the interconnectedness of colonial ambitions and international power struggles. This rivalry ultimately shaped the geopolitical landscape of the time, influencing alliances and conflicts worldwide.
During WW 1, in 1917, America entered the war with their military. Prior to this, America was supplying the Allies with goods. == ==

America's failure in Vietnam resulted in the collapse of its containment policy, as communism was not contained in Vietnam; the country was unified under communist rule following the fall of Saigon in 1975. Additionally, the failure led to a reassessment of U.S. foreign policy and military engagement in conflicts worldwide, contributing to a more cautious approach in subsequent interventions. Ultimately, the Vietnam War left a lasting impact on American society and politics, shaping public perceptions of military involvement.
