Will resignations and a political shake-up in Ukraine negatively affect its war efforts?

No, not at all. This is anti-corruption efforts, getting rid of a bunch of people that are seen as problematic in terms of skimming money within the government. Russia's been more corrupt than Ukraine historically, but actually, it's quite close. There's a lot of work to be done, and as people start thinking about Ukraine attracting major funds from the Europeans, the Americans, others, multilaterals to rebuild the country, they really need to make sure that the money is going where it needs to, and that means running the economy well. So this is the effort that's being tried here, but it doesn't really matter with the war effort at all.
