2. Stay quiet. Snowden has already discussed his motivation for leaking the details of the NSA spy programs, but from now on he should leave that campaign to his surrogates. History has shown that big-mouthed fugitives run the risk of rubbing their hosts the wrong way. The classic example from the Vietnam Era was Eldridge Cleaver, the minister of information of the Black Panther Party. On the run from an attempted-murder charge in California in 1968, Cleaver escaped to Cuba, where he was initially welcomed with open arms by Fidel Castro’s regime. But Cleaver ruined things fairly quickly by speaking candidly to reporters, particularly about the harsh treatment being accorded several imprisoned American hijackers. The irate Cubans forced Cleaver to move to Algeria, where the Soul on Ice author eventually wore out his welcome by publicly calling for dictatorial president Houari Boumedienne to give him the $1 million brought over by a group of American hijackers. Boumedienne had Cleaver’s headquarters raided in revenge.

Snowden doesn’t appear to be quite the loose cannon that Cleaver was, but he should still be aware that his odds of accidentally upsetting his hosts greatly increase every time he opens his mouth on the record.
