All of those things may be true.
But Biden has been lousy as far as Britain is concerned, as I expected. I preferred him to Trump. But I'd like a party in DC that treats us as an ally, not a minion subject to an emotional type of American Irish Republicanism that comes out of the 1990s, combined with a romantic idea of the EU as a sort of American style federation in Europe (which is nothing the British voted to be a part of).
He and Pelosi have done good jobs domestically. But they are not great friends of ours. So that weighs in my balance. I'll be more sympathetic towards DeSantis because he values Britain. It's a shame Biden has been fickle. He had the choice to be a friend. He chose not to be.
A frequent experience of America's relationship with the UK: when the US wants something, we almost always support it; when the UK wants something, we only have your support sometimes. It feels imbalanced. This has been especially true over Brexit where the British people voted to leave the EU and the US has been really unsupportive of the decision and has used the idea of a trading relationship as a means to manipulate UK policy in Northern Ireland (which is part of Britain, not Ireland) and not constructively.
