So I think that one thing that Biden is, is on the right track on absolutely is really this notion of restoring American credibility. It's absolutely no secret that the Trump administration undermined American credibility through through a variety of functions, most notably, their withdrawal for national agreements, they're signaling to Alliance partners that they, they were no longer going to be committed to the Alliance. But also Trump kind of had a bit of a habit, I would say not always, to be fair, not always. But he he did have a little bit of a habit of making these really strong, what I would call bombastic or blustery statements. Using really strong emotional rhetoric, I think, for example, the fire and fury comment, right. And then not always adequately following through on that. So I think the Biden administration is right, to focus on restoring American credibility. However, what my work shows what my book shows, in particular, is that it is not so easy as just saying we we reaffirm American alliances. Right? What my book shows is that Biden's going to have an incredibly narrow time window in which to do this. What I find in the book is that new leaders do establish reputations that are separate from their states and separate from their predecessors, which is good news for Biden, he is not bound by Trump's reputation, or by the rhetorical choices that Trump made. The problem, however, is that what it's going to take from Biden is really clear, consistent rhetoric, and also clear policy agendas. And not just in terms of we want our store American credibility, but explicitly saying how he's going to do that. So for example, Kennedy kind of talked big on what he wanted for Berlin but did not make it clear how he was going to make that happen. And that really came back a little bit to bite him because what that signaled was that he didn't really know how he was going to do it and that he wasn't really prepared. And so what I would like to see from the Biden administration, I know it's very early. Right. And there's lots on the agenda, including a global pandemic. But what I would like to see from the Biden administration, now that his cabinet is getting confirmed, and is really getting settled, is a bit more, you know, nuanced and discussion about how are you going to restore American credibility with Europe? Right, what is this? What is the rhetoric of America's back? Well, what does that mean for European Alliance partners? Right? How are we going to do this? And how are we going to integrate that, I think it's going to be really important for the administration moving forward. And of course, Biden's going to need to very clearly follow through on this, you know, these broader promises with concrete policy action and do that rather quickly. I think that we tend to think about the fact that well, you know, campaign promises, those are for domestic audiences, international audiences, like Putin or whoever, right, they must realize those are for domestic audiences. Right? Yeah, they know, actually, what I find in my book is that Khrushchev used Kennedy's campaign promises as a signal of what he was going to do in the future. And when Kennedy didn't follow through on those campaign promises, it actually undermined his reputation. This is, a few years ago, before the book came out, I actually wrote a piece for foreign policy comm with Peter fever on this on this particular issue. And so I think there is this tendency, particularly on the campaign trail to make these big promises with the assumption that we all know that, you know, candidates over promise, well, the domestic public might, quote, unquote, know that, but international observers, outside observers, they're actually listening. So there is kind of this tension between when leaders make these promises for domestic audiences, they have to recognize that those have international audience costs as well, and be really interesting to see how the Biden ministration follows through on this really, I think, important and lofty agenda that they've put forth. And they do have a really difficult task here of, of, you know, rebuilding America in so many ways. And I'm glad they're doing that. I mean, I'm glad that they're making that front and center. I will be eagerly awaiting to see how the actual policy develops, particularly in the first 100 days here.
