The rationale keeps changing, by Trump and his people. Imminent threat to America? No. Imminent threat to the region? No. What does "imminent" mean? Trump and his people don't know. An embassy targeted? Maybe. 4 embassies targeted according to the latest from Trump? I highly doubt it. Trump ordered the strike to appease some Republican senators? Highly probable. Trump wanted to distract from impeachment? Highly probable. https://www.cnn.com/2020/01/10/politics/trump-iran-mixed-messaging/index.html What's your guess?
