As you may know, an agreement has been reached between Iran and a group of six other nations, including the U.S. The agreement attempts to prevent Iran from developing a nuclear weapon by limiting Iran's ability to produce nuclear material and allowing inspections into Iran's nuclear sites in exchange for reducing certain economic sanctions that are currently in place.

Currently there is some debate about what stance the US should take in relation to the possibility that Israel might attack Iran's nuclear program. You will see three arguments on this issue. Please select how convincing you find each of them. (University of Maryland, March 3-7, 2012; October 2, 2012)

1. The US should discourage Israel from attacking Iran's nuclear program. There are huge risks to US national interests, since Iran may attack US assets in retaliation, pulling the US into a war. Oil prices will skyrocket. Furthermore, US military leaders say the most that could be achieved would be to slow down Iran's nuclear program a bit and probably just lead them to rebuild it underground.

2. The US should take a neutral stance. Israel has a right to take actions it sees as necessary for its own defense. Meanwhile, the US should think about its own interests and make a clear statement distancing itself from whatever Israel may choose to do, to reduce the chance that Iran will retaliate against US targets.

3. The US should encourage Israel to attack Iran's nuclear program. Clearly Iran is trying to develop nuclear weapons, and if Israel will take the heat for stopping or at least slowing down the program, all the better for the US. The risk of Iran acquiring nuclear weapons is of greater concern than the fallout from an Israeli strike.
