In a wave of attacks, the Israeli military struck the Natanz nuclear facility, military bases, and other targets in Iran, and also assassinated Iran’s three top military leaders among many other senior military officials and several nuclear scientists. Israel’s military strikes are likely to set back Iran’s nuclear program, but parts of the program will remain intact to varying degrees, and Iran will seek to retaliate. The resulting mess might lead the United States to become involved, despite the Trump administration’s desire to avoid attacking Iran.
