A nation's actions tend to be semantically categorized by the current hegemony. Or another way to put it, phrases like "terrorism" or "aggressive act of war" or "defense" or "national interest" are given their
Platonic essence (precious fluid?) via the Hegemon. Phenomenological operations may seem quite dissonant from perceived realities, but the hegemon adjusts elegantly and accordingly. (there have been a few creaks as of late)
For example,
bombed back to the stone age is a popular phrase in global politics. "Iran will be bombed back to the stone age unless ____". I'm sure we'll hear that soon enough. If you'll allow me the segue here's an interesting etymology..
Those who control time control the space. Iran has neighbors who want to wind back their clock. The leadership is desperate to "catch up" in time. Before its too late.
From the perspective of the US Government, Iran's leadership seems irrational and crazy, and thus must be attacked. Before its too late.
A phenomenological take on Iran:
