Why should a rebellion in Cuba - become a reason for the United States to war with Cuba?
In the present day if the Cubans rebell against the Castros, then why would the US go to war with Cuba? Wouldn't they rather support the rebelling citizens. After all the Castros are dictators and Cubans are poor and live in a communist state. A rebellion would free them from this strangle hold they have been in for decades.
I would not think a rebellion against Castro(s) would be cause for a war between US and Cuba. Besides in the 1960s didn't President Kennedy try to overthrow the dictatorship in Cuba and failed?
Rather this type of rebellion would be more like the recent rebellion, upraisings, in Egypt, Iraq, Libyia etc. in which the US offered support. In most countries.
