I guess they learned from their mistakes
Operation Red Dog was the code name of a 1981 military filibustering plot by Canadian and American citizens, largely affiliated with white supremacist and Ku Klux Klan groups, to overthrow the government of Dominica, where they planned to restore former Prime Minister Patrick John to power. The chief figures included American Klansman Mike Perdue, German-Canadian neo-Nazi Wolfgang Droege, and Barbadian weapons smuggler Sydney Burnett-Alleyne. After the plot was thwarted by US federal agents in New Orleans, Louisiana, the news media dubbed it "Bayou of Pigs", after the failed 1961 Bay of Pigs invasion.

So don't run around with Nazi flags, instead call yourself "alt-right", support a media that turns your enemies into the enemies of the public, get support from an autocratic regime (Russia), and be OK with supporting some billionaire (maybe) with shifting beliefs and where you failed in 1981, you might succeed in 2016.
