I would not advise overreacting to the Iranian response to the recent US missile strikes.
Iran struck back at the United States for the killing of a top Iranian general early Wednesday, firing a series of ballistic missiles at two Iraqi bases housing U.S. troops in a major escalation that brought the two longtime foes closer to war…. Iran has started its “second round” of attacks against bases holding U.S. troops in Iraq, the Tehran-based Tasnim news agency said on Wednesday. The second round of attacks started an hour after the first phase took place, the agency reported.
This is not what countries do when they have any intention of engaging in actual war. The Iranian military has more than 500,000 active troops and there are no reports of them being deployed aggressively in the direction of Iraq or Saudi Arabia.
This is just tit-for-tat. If Iran was serious, they would be deploying divisions and shutting down all naval traffic in the Gulf. Until they start doing that, I wouldn’t even bother paying the whole thing any attention.
