I think what we've seen since the Iraq and Afghanistan debacles is a pivot towards a "de-development" strategy. The goal is simply to just collapse, sew chaos, and generally destroy the state capacity of enemy nation states as much as possible, with no pretense of trying to transition the government to a friendly regime. One reason to do that is that you don't need an occupation, with the corresponding risk of high casualties and the risk that the whole endeavor be perceived as a failure.

We see a complete version of this strategy being employed against Iran: air strikes, special forces operations, clandestine operations, cyber warfare, and economic warfare. It's incredibly devastating to the whole society, there's very little risk of casualties, and there's very little risk of it being perceived as a "failure" on the political stage (even when the regime doesn't collapse).

More limited versions of this are applied to other countries, notably Cuba, North Korea and Venezuela. We see the results of it completely collapsing a state in Libya. We see examples of other countries doing it; I think the best example being Israel and Lebanon.
