Invade Who? U.S. Invasions have been generally been motivated by several causes: - National Security- If a country is believed to be a direct threat to America's safety (such as possessing WMD's or Harboring terrorists) it could be a target for invasion -To Protect Allies- Many wars such as Vietnam or the Korean war were fought to protect American Allies, and keep a reputation of protecting those who are friendly to America. -To contain communism- The policy of containment caused a lot of wars -To get resources- Unfortunately, a lot of our wars (especially the earlier ones) were to obtain resources or territory from weaker nations
There are multiple reasons why America entered the war in 1917. In 1915, the Lusitania sank after being torpedoed by German submarines. 128 Americans aboard were killed. In early 1917, Germany's foreign minister sent a telegram to Mexico promising German aid if Mexico would invade America. The offer was meant to keep America out of Europe, but Britain intercepted it and sent it to America. The German policy of Unrestricted Submarine Warfare was a threat to American shipping. The Germans would sink any vessel they thought was headed for the Allied Powers or their colonies. The submarines flooding the Atlantic also threatened US port cities, leading to the rearmament of the system of forts built in the mid-1800s as well as the construction of new ones. That would cost more and more money as the war raged on. And, if the Allied Powers lost, they would be unable to pay back the money America had given them as credit to buy US-manufactured supplies.
America Joined the WW1 conflict in 1917, 3 years after the war started. The threat of unrestricted U Boat activity, American business interests with Britain and France , and German dictatorship were factors. Also Germany offered to take up arms with Mexico against America.
