Iranian Nuclear Program Under Attack (again)
While these assassinations aren't new by any stretch of the word, they show a concentrated effort to prevent them from developing these weapons. While no country is owning up to the attacks, the flawless execution and organization of these attacks make it clear somebody doesn't want them to have nuclear weapons.
These attacks come after the Stuxnet worm, which damaged Iranian equipment and severely set back their nuclear program. These newer attacks are much more aggressive than attacking a computer network, and they send a clear message to the Iran that whoever is behind them is going all in.
Iran's own counterattacks have started being launched at Israel, the prime suspect for the attacks on Iran's nuclear program. It's a tense time in an already unstable region, with tempers flaring and attacks going in both directions it looks like it's only a matter of time before a conventional war begins.
