Fresh off Russian President Vladimir Putin’s “victory” of a fifth term, the Kremlin on Monday said it would move to establish a buffer zone in Ukrainian territory for the sake of Russia’s security. Putin suggested creating a “'sanitary zone' in the territories today under the Kyiv regime.”

What’s this all about? While the bulk of the fighting in the Russia-Ukraine war has occurred within Ukrainian territory, Kyiv has regularly launched strikes against targets in Russia proper as well. The border city of Belgorod has been a frequent target. The Kremlin said a buffer zone would aim to ensure “any means that the enemy uses to strike us are out of range."

Moscow already illegally annexed four Ukrainian territories — Donetsk, Kherson, Luhansk, and Zaporizhzhia — in 2022 (despite not fully controlling these regions). But Russia in recent months has ramped up strikes on Kharkiv, a region along the Ukraine-Russia border. Talk of a buffer zone could signal that Russia will increasingly prioritize seizing territory in Kharkiv.

Ukraine raises the alarm. Kyiv says this signals that Russia is planning to escalate the conflict, which has largely been stalemated over the past year, though Russia last month seized Avdiivka — giving it new momentum in 2024.

But he has signed just five new bills into law, a historic low, and many of his EOs are facing legal challenges. Trump’s controversial executive orders have grabbed plenty of headlines, but what about the less-contentious ones? We know it’s a lot to keep up with, so here are a few you may have missed:
