Fair-and-balanced Fox News reported on Wednesday that "Cuban military operatives reportedly have been spotted in Syria, where sources believe they are advising President Bashar al-Assad's soldiers and may be preparing to man Russian-made tanks to aid Damascus in fighting rebel forces backed by the U.S." Fox's claim of an imaginary enemy alliance relies on two sources: the University of Miami's Institute for Cuban and Cuban-American Studies and an anonymous U.S. official.
The source at the Miami Institute indicated that "An Arab military officer at the Damascus airport reportedly witnessed two Russian planes arrive there with Cuban military personnel on board. When the officer questioned the Cubans, they told him they were there to assist Assad because they are experts at operating Russian tanks."
It is unclear what nationality the "Arab" officer was. Perhaps, said Arab determined the people aboard the Russian plane were Cubans because he saw them smoking cigars and drinking mojitos. However improbable this may seem to an unbiased observer, the source from the Miami Institute said that "it doesn't surprise me."
The supposed U.S. official - to whom Fox grants anonymity without giving a reason why - related "evidence" from "intelligence reports" that Cuban troops "may" have trained in Russia and "may have" come to Syria in Russian planes. Sounds legit.
By Friday, the story had gained enough traction that it was raised at a White House briefing. In a response that should have been enough to put the story to rest, the White House Press Secretary said "we've seen no evidence to indicate that those reports are true."
But a few hours later, the Daily Beast had definitively declared in a headline that: "Cuba Is Intervening in Syria to Help Russia. It's Not the First Time Havana's Assisted Moscow."
In reality, Obama's "gesture of goodwill" is little more than behaving less overtly hostile after decades of American aggression against Cuba and Iran. If you are choking someone unprovoked and you loosen you're grip, it is far from a gesture of goodwill.
Bloodworth also tries to make a historical argument that Cuba's (imaginary) military actions in Syria are consistent with their "bloody" interventions elsewhere. He decries "Cuban terror in Ethiopia" that resulted in hundreds of thousands of people being killed. "The tragedy was largely a consequence of the policies pursued by the Communist dictatorship that ruled Ethiopia at the time - a regime propped up by Cuba and the Soviet Union."
In 1977, Somalia had invaded Ethiopia in an attack that "had been encouraged by ambivalent signals from Washington," according to historian Piero Gleijeses in his book Visions of Freedom. Initially reluctant to become involved, Fidel Castro finally agreed to Ethiopian requests to send troops to repel the Somali invasion.
Gleijeses found in his extensive review of formerly classified military documents that Cuba's motives in aiding Ethiopia were sincere:
With hindsight, we know that Mengistu's policies resulted in disaster, but this was not clear in 1977: though the process was undeniably bloody, the Ethiopian junta had decreed a radical agrarian reform and taken unprecedented steps to foster the cultural rights of the non-Amhara population... The evidence indicates that the Cubans intervened because they believed, as Cuban intelligence stated in March 1977, that 'the social and economic measures adopted by Ethiopia's leadership are the most progressive we have seen in any underdeveloped country since the triumph of the Cuban revolution.' In addition to correcting the record on Ethiopia, Gleijeses' study also serves to set the record straight on Cuba's historical modus operandi in its military interventions abroad. Cuba did maintain a large military presence in Angola for nearly 15 years, starting in 1975.
Castro first sent troops in November 1975 after Angolan President Agostinho Neto warned of a South African invasion of the country already underway which would inevitably topple the nascent government without outside support. Cuba agreed to send soldiers to Angola right away. Several months later, they would repel the apartheid army back to Pretoria. They remained in Angola at Neto's bequest to prevent further incursions from the racist South African army into the country's sovereign territory.
Castro was adamant that Cuban troops would be responsible for preventing a South African invasion, while Angolan troops should deal with their own internal conflict. In meetings with Neto, Castro "kept hammering away on the need to fight the bandits ... He explained to us that the fight against the bandits was necessarily and without question the responsibility of the Angolans, that (Cuba) could not wage this war, that it was their war." 
Cuba's position during the Angolan conflict is consistent with the diplomatic approach they have repeatedly espoused in Syria, that the Syrian conflict is a domestic problem for the Syrian people and government to resolve themselves, while the international community works to achieve a peaceful solution.
"Cuba reiterates that international cooperation, based on the principles of objectivity, impartiality and non-selectivity, is the only way to effectively promote and protect all human rights," Cuban representative to the UN Human Rights Council Rodolfo Reyes said at a meeting in Switzerland. He added that "Cuba is confident of the capacity of the Syrian people and government to solve their domestic problems without foreign interference."
