At the micro level, on the other hand, I think it can sometimes make a major difference who your secretary of state is. Take, once again, John Kerry. There is a country where America has considerable influence, where John Kerry specifically has exceptional influence, and where American diplomatic intervention can often have significant positive effects on the human rights of at least small groups of people. That would be Vietnam. Mr Kerry, the decorated Vietnam War vet-turned-peacenik, is hugely popular in Vietnam, widely praised for the key role he and John McCain played in the 1990s in settling the POW-MIA issue and re-establishing diplomatic and trade relations. Not only does he enjoy excellent direct relations with Vietnam's communist leadership, he is personally famous. His picture features in propaganda displays in a dozen Vietnamese museums, celebrating what the government presents as America's atonement for its wrongheaded policies during the war, along with Vietnam's re-emergence as an accepted member of the international community with a queasily friendly, if somewhat fraught, relationship with America.
This would put Mr Kerry in an excellent position to lobby for small but meaningful changes in Vietnamese policy, such as, say, freeing the human-rights lawyer Le Quoc Quan, whom Vietnam arrested Thursday on charges of tax evasion.
Let's be clear: Le Quoc Quan is not in jail because of tax evasion. This is his third stint in jail. The first time, he was arrested on his return from America in 2007 because he'd had the temerity to accept a fellowship to study democratic politics at the National Democratic Institute. After returning to Vietnam, he repeatedly defended dissidents and bloggers in court, demonstrated at rallies for Catholic freedom of worship and against China, and got himself involved in various other politically irritating activities. He's in jail now because Vietnam is engaged in a bout of anti-blogger disciplinary activity, clearly related to the country's lacklustre economic performance, corruption scandals and power struggles in the intertwined world of government-business cronyism, and rising popular dissatisfaction.
Vietnam has a lot of dissidents in jail. America is not going to be able to get Vietnam to stop arresting dissidents; the Communist Party is not interested in political suicide. Nor will it be able to force Vietnam to allow its citizens to do whatever they want on the internet. But Vietnam is dependent on American export markets and on American military and diplomatic backing in its struggle against China over maritime jurisdiction in the South China Sea. That allows America to make it clear that Vietnam will pay a limited price, in embarrassment and ebbing support, if it goes beyond certain informal lines in its oppression of dissidents. John Kerry, by virtue of his personal qualities, is in a position to draw those lines somewhat more expansively than a different secretary of state would be, one who was not considered by Vietnam to be a hero of Vietnamese-American reconciliation. He should use that position to try and get Le Quoc Quan and some of his fellow democracy activists out of jail. And I'm pretty optimistic he will.
