From Chuck Todd, Mark Murray, and Domenico Montanaro *** Ramping up the rhetoric: As the violence and protests escalated in Iran on Saturday, President Obama stepped up his criticism about what’s happening there. “The Iranian government must understand that the world is watching,” he said in a statement. “We mourn each and every innocent life that is lost. We call on the Iranian government to stop all violent and unjust actions against its own people. The universal rights to assembly and free speech must be respected, and the United States stands with all who seek to exercise those rights.” But the toughest domestic political rhetoric on Iran is coming from Republicans. This is one of those cases where Democrats and the White House are wondering what the reaction would be if the roles were reversed — i.e., Democrats criticizing a GOP administration’s response on foreign policy. Indeed, Republicans regularly beat up Democrats for supposedly politicizing international issues (do remember that the establishment Democratic Party didn’t start truly criticizing the situation in Iraq until two-plus years after the war began). But who’s politicizing now? Also, it’s worth noting that the criticism from Republicans is NOT universal. In fact, the GOP establishment on this issue is more divided than the coverage is suggesting.
