1. The US should take a hard line against its citizens traveling to Iran. That’s for their own protection. An American in Iran is a potential hostage. And since we haven’t yet mastered the Rooseveltian art of declaring, “Perdicaris Alive or Raisuli Dead”, we’re vulnerable.
2. Iran is testing us. Failing that test would be dangerous and will mean an escalation of violence on other fronts.
3. One potential trigger for this may have been the planned withdrawal from Syria. That doesn’t mean the withdrawal is wrong, but that Iran may see it as a capitulation, even though it has nothing to do with Iran, and may be probing to see if we’re vulnerable now.
That’s how terrorists operate. And that’s why it’s important to forcefully push back when they do.
