PARIS – At the Cold War’s outset, there was an intense debate in the United States between those who wanted to contain communism and those who wanted to roll it back. Was it sufficient to fix limits on the Soviet Union’s ambitions, or was a more aggressive stance, sometimes described as “containment plus,” necessary?
The recent spat between US President Barack Obama and his former secretary of state (and possible successor), Hillary Clinton, seems to have revived that debate. But are its terms of reference useful today, as the West faces the simultaneous challenges of the Islamic State in the Middle East and a revisionist Russia? Are Western leaders right to assume that the two challenges are distinct, and that containment will suffice in the case of Russia, while rollback is absolutely necessary in the case of the Islamic State?
