the question, though, is, there is tension between president biden and president zelenskyy. the issue is, again, exactly what arms are going to be supplied and, even more, how can they be used? what zelenskyy wants is not simply more arms sooner, but he wants a slightly greater envelope in terms of where and how he can use arms against russia. the united states is trying to balance what happens on the battlefield against, how would i call it, provoking russia to escalate, and there is also a tension underneath the surface between the united states and zelenskyy, not only over all this and the uncertainty of if donald trump were to be elected, but what ought to define success? mr. zelenskyy wants to liberate all the territory he lost, not just since 2022 but, more important, since 2014. people like me look and say, that's not wildly realistic. the definition of success may have to be dialed down. that's underneath it all. what do we have to accomplish here?
