Israel is considering a strike on Iran's nuclear facilities despite the US being unwilling to support such a move at this time. Israeli officials have proposed a range of options to attack Iran, including airstrikes and commando operations. The plans vary in severity and could set back Iran's nuclear program by months or more. Israel now believes it could launch a limited strike on Iran that would require less US support. However, it is unclear if or when Israel would move forward with such a strike, especially with talks on a nuclear deal getting started.
