As part of its recent war on Iran, Israel has killed around 14 Iranian scientists who worked on the country's nuclear program. In some cases, the scientists were killed along with their families. This is part of Israel's longstanding effort to delay Iran's nuclear development. But some experts have raised concerns about the legal and ethical implications of these assassinations.
