I don't really know if this will answer your question but I think it will because when the Japanese attacked Pearl Harbor and when the war was ire we agreed that I'd Japan ever gets in a war again that we will be there to back them up and the same to us. Sorry if this doesnt answer your question
Im not sure if there are options, but one of the major reasons the U.S. oversaw the building of the Panama Canal was to increase the mobility of the U.S. naval fleet. That way if there was ever an attack on the Pacific or Atlantic, ships could easily navigate between the two oceans through the canal, I think. Hope this was helpful :P

goods. This was to make imported items more expensive than domestically

American jobs and making northern manufacturers wealthy. It was bitterly
resented in the south. The south traded a lot with Europe, particularly
France and England.</span>
