No one who cares about Latin America and the Caribbean wants anything to do with a U.S. military intervention or backchannel interference. People still have memories of Grenada and Panama, which were unmitigated disasters (tbh, no one except a small group of elites wanted the U.S. back then either).
I'm just saying that, in terms of interest, I don't see the same type of hue and cry for even the smallest of diplomatic measures to be taken, the way I've noticed with Syria. Then again, Yemen is being completely ignored and people are starving to death there, so I guess there's really no predicting what will capture the interest of countries like the U.S.
