The summer before the 2020 election I was working on some cybersecurity outreach with CISA, UofO, and DHS. The guy from DHS pivoted half the discussions into how much worse that topic had become for them since the Iran Deal was cancelled by Trump. A not-entirely-intended (but well understood) benefit of the deal had been that Iran wasn’t willing to risk it ending by partaking in any overt cyber offensives against the US.
