Large scale deployments shifted under Obama to widescale bombing campaigns. The site mentions its various sources such as this [1] which mentions that Obama also increased the number of drone strikes by an order of magnitude relative to his predecessor. To be clear I'm not picking on Obama, but saying solely that this isn't a partisan issue. "They" all love war.
And places being in a state of internal conflict, conflict which is itself often backed and fomented by US intelligence agencies and backed proxy forces, is hardly some reason to go bomb them. Even moreso when you look at results. See what Libya turned into, and what Syria is now turning into. It turns out that Al Qaeda in a suit is still Al Qaeda, to literally nobody's surprise if you're even vaguely familiar with our history of backing extremists and putting them in power, something which we have done repeatedly.
This war, if it escalates, is not going to be good for Iran, the people of Iran, or likely even the US. The only country that might come out a winner is Israel, but even that might not end up being the case, as Iran's retaliation will likely focus on them. To say nothing of longer term consequences.

Drone strikes picked up, obviously as that technology became more and more mature. They're cheaper to operate and don't put a pilot in harms way. So that's kinda expected?
Agreed with most of the rest you said though

This isn't true. Small-scale targeted raids, not B52s recreating Dresden.
