It is a bit of both; appears as another phase in the current messy ceasefire. The US framing (focused on military targets, described as completed) indicates they are looking for a diplomatic off-ramp, not a planned long-term escalation. It is a spike in tensions, likely provoked by the helicopter shoot-down, and unless something unpredictable happens, it should revert to the messy ceasefire.
The way President Trump has framed the attacks, the way CENTCOM described them as completed, the fact they are focused on military targets.
