America has gone back to doing what it does best - bombing Iraq - although the justification varies.
Was it pre-emptive or defensive? Which is it? Who cares?

The U.S. military conducted a defensive airstrike south of Baghdad, Iraq, on Tuesday, according to two U.S. officials.
"U.S. forces in Iraq conducted a defensive airstrike in the Musayib in Babil Province, targeting combatants attempting to launch one-way attack uncrewed aerial systems (OWAUAS)," one of the officials told ABC News...

Earlier on Tuesday, Iraqi officials had reported blasts in an area south of Baghdad that is a hub for Iraq's Popular Mobilization Forces, the umbrella name for Iranian-backed militia groups operating under Iraq's Defense Ministry.

A statement provided to ABC News by the Popular Mobilization Authority said, "Forces affiliated with the 47th Brigade… were exposed to an explosion of unknown nature, which resulted in the martyrdom of a number of people and the injury of others."

It might be worth noting that the Iraqi government was not happy about their country being bombed.

(Reuters) - International coalition forces in Iraq committed a "heinous crime" by targeting security sites, Iraqi military spokesman Yahya Rasool said in a statement on Wednesday.
Rasool called the attacks a serious violation of the coalition's mission and mandate. The United States on Tuesday carried out a strike in Iraq in what U.S. officials described as self defence.
