Any sensible administration implementing such an obviously suspect tariff regime could have easily put the tariffs in a kind of escrow instead of just pretending it's novel policy was trivially constitutional.

Blaming SCOTUS here is not out of the question, but they should not be "entirely" to blame, unless you think it's totally fine to run the Executive branch like you're trying to get away with something. It's not.

Right. I’m okay with blaming both.

Of course not, you're right. I think the parent comment implies the responsibility of the Trump administration, the same way criticizing a botched police response implies blaming a mass shooter for a crime.

A sensible administration would not have used emergency powers to implement worldwide tariffs because they don't like how the world economy is shaping.
