Okay, nobody got this one. So here's the answer:
The country was Imperial Germany. The provocation was the US presence in the Phillipines at the time of the Spanish-American War. The Kaiser had had his eye on Phillipines himself at that time and had been building up his naval forces in China to be able to conquer the Phillipines. When Commodore Dewey defeated the Spanish at Manila, the Kaiser was enraged and sent a task force to Manila in response. Dewey faced them down. Though the Germans had larger more powerful ships in greater numbers, he didn't blink - they did and backed down. This only enraged the Kaiser further and he had his General Staff draw up war plans for the conquest of America. By 1900 the plans were in place and forces were being prepared. The Kaiser vascilated on this from that point until about 1904 when his eye turned to Britain and the naval arms race with that nation that led to WWI. Many feel that only the Kaiser's inability to stay focused saved the US from conquest. This inability was a symptom of his health problems. Germany most certainly would've conquered us if they had attacked at that time. We had no large Army and our Navy was still quite small then. Mass attacks on New York City, Washington, D.C., and Atlanta as the Kaiser's war plan called for would've succeeded.
Okay, here's an easier question for the next one.
The US military was segregated until July 26, 1948 when President Harry Truman issued Executive Order 9981. The order brought an end to racial segregation within the ranks of the United States military forces. Before that, it was considered a great stride just for non-whites to be allowed to fight for their country at all. Many of you have seen the movie "Glory" which illustrates just that occurance. For 400 milbucks name the first non-white unit in the US military.
