1898:  USS Maine and The Spanish-American War

“Remember the Maine, to hell with Spain”

The modern era history of Cuba pre-dates that of the USA.  Spain claimed Cuba in 1492 when Christopher Columbus landed there.  The Italian explorer was working for the Spanish Crown.  British settlers, on the other hand, colonized Jamestown, Virginia more than a century later, in 1607.

As America expanded in the years following, it kept one eye on Cuba, as it did on other Spanish territories, e.g. Philippines, Guam, and Puerto Rico.

Spanish overlords ruled the Cuban natives harshly for many years;  a series of rebellions took place in the 19th century (1826, 1829, 1837), and rebellion was in the air again by the late 1880s. U.S. newspapermen like William Randolph Hearst and Joseph Pulitzer took up the rebel cause.

When riots broke out in the capital Havana, on January 25, 1898, the U.S. sent the U.S.S. Maine to the Havana harbor to quell the disturbance, and protect U.S. civilians there tending to sugar and tobacco businesses.  On February 15, the Maine exploded;  266 of the 355 sailor aboard were killed.

Hearst and Pulitzer immediately blamed Spain and called for war.  The New York Journal headlined "Spanish Treachery."  “Remember the Maine, to hell with Spain” would become a handy slogan.  The Navy, for its part, blamed a mine for the explosion, but refrained from blaming Spain.

Feelings over facts held sway for many.  We find a good example of this feeling in a February 16 letter Theodore Roosevelt wrote a friend saying, “Being a Jingo, as I am writing confidentially, I will say, to relieve my feelings, that I would give anything if President McKinley would order the fleet to Havana tomorrow. This Cuban business ought to stop. The Maine was sunk by an act of dirty treachery on the part of the Spaniards, I believe; though we shall never find out definitely, and officially it will go down as an accident.”

President McKinley was indeed amenable.  Backed by Congress, McKinley put on a naval blockage of Cuba on April 21.  Spain declared war on the U.S. April 23, and the U.S. followed suit, April 25.  War lasted until August 12, 1898. 

President McKinley went to Congress and got permission to place a blockade of Cuba on April 21st. Spain then declared war on the U.S. on April 23rd and immediately following the U.S. followed suit and declared war on Spain on April 25th. The war lasted to August 12, and ended with a U.S. victory.   The Treaty of Paris (signed December 10, 1898) provided for Spain to cede control of Cuba, The Philippines, Puerto Rico, Guam, and parts of the West Indies.

This marked the end of Spain as world empire, and the taking up of that mantle by the U.S.

Circling back, did Spain actually sink the Maine? In 1911, the Department of the Navy brought up the remains of the ship and undertook another investigation that returned the same conclusion:  a mine did it.

Other investigators thought it possible that there was a spontaneous combustion of coal sitting next to the magazine of ammunition in the forward hull. They said the evidence supporting this was that the blast blew outward from the hull and not inward as a mine would cause.

The Spanish never claimed responsibility for the blast.  In fact, their officials and civilians from the adjacent Spanish cruiser Alfonso XII helped the survivors from the blast, making it unlikely that Spain was itching for war vs. the U.S.  As a result of this assistance from the Spanish, as well as another U.S. ship anchored nearby, some 100 lives were saved.

If this was a false flag, i.e. not the work of the Spanish, it illustrates that a government can manipulate a tragedy to its own end -- whatever the genesis of it.  In the modern parlance, "never let a crisis go to waste."

==============================================

Final thought:  if nearly two weeks after Las Vegas Massacre, we don't have clarity on the who/what/where/when/how, etc., how much less will we know about what happens in the sea offshore Korea.  Putting major military assets offshore an adversary, may be regarded as one step lower than a naval blockade which is usually construed as an act of war.  Ships offshore are, at the least, a provocation.  Reminds one of the old school street saying, "if you pull a gun on me, you better use it."

Mr. Trump, while we are still in this "calm before the storm," as you say, have you thought this out, step by step, to its full conclusion, all the possible if-thens?  Humanity wants to know.
