Russia has made some crucial advances in the northeastern part of Avdiivka, and are pushing into the city center. Multiple Ukrainian sources have reported that the situation there is not good, and that the city will fall without additional reinforcements. The two major shortages effecting Ukraine here currently are manpower and ammunition. The latter is unfortunately partially the result of western aid being held up for so long, but the former is a major problem that Ukraine has yet to find a satisfactory answer to. And with the situation between Zelenskyy and Zaluzhnyi still awkward and with Zaluzhnyi not yet having been officially fired or replaced, it doesn't seem as if Ukraine is about to settle on a solution any time soon.
On that note, Zelenskyy has stated that a broad reset of leadership is needed in Ukraine. He didn't single out Zaluzhnyi here, which strongly suggests that there will be other major shakeups in the near future (and, presumably, Zaluzhnyi will be officially fired). The United States, at least publicly, has stressed that they are okay with Zaluzhnyi being removed, citing Ukraine's sovereignty. This seems to be the main position among Ukraine's allies; it's an internal Ukrainian matter, and should be handled accordingly.
It's also worth noting that Zelenskyy visited Robotyne, one of the few settlements that Ukraine captured during their 2023 offensive and has managed to hold onto. Zelenskyy is no stranger to popping up at parts of the front itself, but his visit feels rather pointed given the ongoing spat with Zaluzhnyi. Robotyne was the focal point of the failed offensive, which Zelenskyy and Zaluzhnyi both had different ideas on how to carry it out.
Politics in the United States continue to move rapidly, but without any clear solution to continued funding for Ukraine. The two chambers of the legislative branch are currently moving in opposite directions, and a funding bill requires the approval of both, as well as Biden. The Senate has put forth a bipartisan triple bill, which would see funding go to Ukraine in an amount that would rival the EU's recent package, as well as support for Israel and funding for increasing border security along the border of the United States and Mexico. Meanwhile, the House is currently trying to decouple these different things, and is instead pushing for more partisan, stand alone bills.
However, other Ukrainian allies are looking to advance major packages for Ukraine. In particular, Canada, France, Germany, and Sweden are reportedly planning on providing Ukraine with "assurances" over the coming weeks. These will likely be similar to the massive drone-focused military aid package that the United Kingdom announced a few weeks back. In the case of Sweden, it might contain Gripen warplanes, but this is largely dependent on whether or not Hungary caves and let's Sweden join NATO. Sweden is reportedly reluctant to part with the planes until they have the strong mutual defense clause of NATO to protect them.
