Gulf coast PADD3 refineries = disproportionate production of diesel, aviation, bunker fuel for CONUS use. Something like 70% of all refined products used in US comes from PADD3, other refineries cannot replace PADD3 complexity/production levels (think specialty fuels for military aviation, missiles etc). US economic nervous system is EXTRA exposed to gulf coast refinery disruptions. PADD3 refineries (or hubs / pipelines serving east/west coast which more singular point failure) itself enough to cripple US with shortages even if all exports stopped. Gulf gas terminal is for export i.e. doesn't materially impact CONUS, it's deterrence conventional counter-value target. There's also offshore terminals. The broader point being gulf coast has host of targets along escalation/deterrence ladder.
Yes, I'm not disagreeing that there are lots of interesting things to hit on the Gulf coast. PADD3 is just another way to say "gulf" refineries, it's a location not a technical specification.
Other refineries can indeed take up the slack. Especially if the US stops exporting. Trains can deliver fuel, trucks. The US military would not be crippled, most certainly, and the domestic US would see primary production kept in-nation, not exported.
I'm not sure why you think that only Gulf refineries can make jet fuel.
NOTE: I'm not saying it wouldn't be a key attack vector, or non-disruptive. I'm just saying the US would do what it always has done, as any nation would do, it would ensure survival first, and so the rest of the world would suffer far more.
