In a visit to Qatar and Saudi Arabia this week, Hillary Clinton said that Iran "is moving toward a military dictatorship," and continued the administration's campaign for tougher sanctions against that country.
What could America's top diplomat hope to accomplish with this kind of inflammatory rhetoric? It seems unlikely that the goal was to support human rights in Iran. Because of the United States' history in Iran and in the region, it tends to give legitimacy to repression. The more that any opposition can be linked to the United States' actions, words, or support, the harder time they will have.
Second, it is tough for anyone – especially in the region – to believe that the US is really concerned about human rights abuses. In addition to supporting Israel's collective punishment of the Palestinians in Gaza, Washington has been remarkably quiet as the most important opposition leaders in Egypt were arrested as part of the government's preparations for October elections. Amnesty International stated that the arrestees were "prisoners of conscience, detained solely for their peaceful political activities".
So what is the purpose of a speech like this? The most obvious conclusion is that it is to promote conflict, and to convince Americans that Iran is an actual threat to their security. Americans generally have to be prepared and persuaded for years if they are to accept that they must go to war. The groundwork for the Iraq war was laid during the Clinton presidency. President Clinton imposed sanctions on the country that devastated the civilian population, carried out bombings, and publicly declared that Washington's intention was to overthrow the government. Although, as we now know, Iraq never posed any significant security threat to the US, President Clinton spent years trying to convince Americans that it did.
