Moon of Alabama has the article U.S. Will Come To Regret Its Assassination of Qassim Soleimani.

Today the U.S. declared war on Iran and Iraq.

War is what it will get.

Earlier today a U.S. drone or helicopter killed Major General Qassim Soleimani, the famous commander of the Iranian Quds (‘Jerusalem’) force, while he left the airport of Baghdad where he had just arrived. He had planned to attend the funeral of the 31 Iraqi soldiers the U.S. had killed on December 29 at the Syrian-Iraqi border near Al-Qaim.

I have no idea whether or not Iran has the capabilities of making good on its threats. This is the type of thing for which I coined Greenberg’s Law of Idle Threats.

Never make a threat you don’t intend to carry out. If you have any doubts about your ability to carry out the threat, do not make it.

Corollary:

If you never test the opposition about whether they make idle threats, then you enable them to ignore this law.
