> There were definite geopolitical signals of an impending conflict - ie. warships moving into the region, Iran increasing oil exports just days before the attack.

As a noob to this area, how would [Iran increasing oil exports] indicate [higher chance of impending conflict]? Is the idea that Iran exported more oil to raise some funds in expectation of the conflict? Surely if Iran expected conflict it would have done more than just increase oil exports?

It could signal potential disruption to the Strait of Hormuz.
