The US has been a part of both WWI and WWII. We have allies in Europe and South America. We have signed treaties ad made alliances with other counties. I believe that these alliances are important to maintaining a strong military and an imperialist government and country. If our allies are in war or combat and they call out to us for help, being an allies it is our job to back them up. We have their back and they have ours. Having that relationship is important.
Now in the past we the United States have tried to avoid getting involved in the war because sometimes it is none of our business. But if our people are involved or killed and we are antagonized, that is when we get involved.
The USS Main has American civilians aboard and the ship was sunk and they all died. In that situation we will take action to protect our people. We shouldn't get involved unless our allies need us or unless we need to defend ourselves. In some situations war is an opportunity to create alliances and treaties but violence should never be what brings that together.
If a situation were to lead to a war or a world war it may be the right thing to intervene and try to avoid it whether or not it would involve us or not. The economic situation or several countries is poor and none of us meaning countries in the world can afford another world war.
