Why didn't Trump hammer Biden on his support for the Iraq War the way he did Clinton?

[sting in the rafters]

Throughout 2016 Trump used Clinton's support for the 2003 invasion of Iraq as another way to paint her as a tool of the failed political establishment. Obviously Biden was even more hawkish than Clinton, regurgitating the Bush administrations claims of WMDs as well as marshaling support in the Senate. Why didn't Trump come out against Joey the same way? I understand foreign policy played almost no role in the 2020 campaign, though even that small of a differentiation could've made the difference in a close election.

I’m pretty sure foreign policy helped Trump as the R incumbent among nonwhite voters.

True, much has been made of Big T's strong support with Cubans for his hard-line on communism. Though I wonder how much of that was Trump doing historically well with self-described conservatives in general.

They did it in the primary and had no effect. Also Trump had Iraq war supporters in his cabinet

Himself among them, given that he too initially supported the war, no matter his false after-the-fact claims to the contrary.

I mean Pence strongly supported the war as much as any neocon but that didn’t stop
him from attacking Hillary
