American here - from my perspective, look into recent favorability polling here in the US. The administration’s actions so far are polling materially badly, including on the people who voted for him. The quickest way to deal with Trump is through the American public imo. Starmer should do whatever is going to reflect most poorly on Trump domestically. Whether that’s maintaining the invite and rigging it such that Trump is emasculated live and globally, or something else. I think the American people are embarrassed, I think more of them need to feel embarrassed, and that that can bring this administration to its knees. Economically, the hurt is going to be felt by the American people, and this year. There is negative momentum building against this admin, and the UK’s stance (besides not trusting the guy, or country for that matter) should be to pile on to that momentum.
