This is extremely unwise

Poking the wingnuts in the eye on something that doesn't have a popular constituency is not what I would choose to do immediately before taking up the contentious Ukraine bill that everyone is revved up about. And he's already bungled passing this multiple times

Johnson has spent months drawing out Ukraine funding and making it as excruciating as possible in a way that maximizes political pressure and blowback for himself and real world battlefield damage for Ukraine.

1000% smarter move: just pass a damn bill and get it over with

What is evident with both this and Ukraine/natl security is that Johnson does not know what to do, he does not know what he will do, he does not know how to pass these things, and he does not know what will happen. He just isn't very good at this
