Looks like it yes. There was a federal inquiry to determine who sank the Maine in Havana but it was determined that they had no idea who was responsible. Spain had wooden ships at the time and the U.S. had about half steel ships. The last thing Spain would have wanted was war with the U.S. In addition to that the U.S. press was spilling full tilt propaganda depicting Spain as beasts that would kill women and children. The entire thing looks like a set up. In addition to that you have the words of Smedley Butler.
Smedley Butler was a Marine Corp. Major General, that was the highest rank at the time. At the time of his death in 1940 he was the most decorated Marine in U.S. history. He wrote a book called War is a Racket in which he said that the reason he went to Cuba and kicked Spain's ass was to make it a nice place for the National City Bank to make revenues off the sugar crop, that world's largest at the time.
National City Bank was owned by the Rockefellers. It loaned the U.S. government 200 million dollars to pay for the war in Cuba. The New York Journal was run at the time by William Randolph Hearst who paid bribes to spy on the Spanish-American ambassador and the De Lome letter was intercepted that called our president weak. Hearst published the letter under the title, "Worst insult to America ever" and then 2 days later the Maine mysteriously sank. So the Rockefellers paid for the war then set up banks all over Cuba and the New York Journal handled the propaganda at home to piss everyone off.
Our media was posting shit like this.
Mark Twain later wrote,
"How our hearts burned with indignation against the atrocious Spaniards.… But when the smoke was over, the dead buried and the cost of the war came back to the people in an increase in the price of commodities and rent — that is, when we sobered up from our patriotic spree — it suddenly dawned on us that the cause of the Spanish-American War was the price of sugar."
