Russia has escalated its aerial bombardment against Ukrainian infrastructure targets, launching a massive overnight assault involving 653 drones and 51 missiles, most of which were reportedly downed by Ukrainian authorities. One significant strike hit a railway hub in Fastiv, a town outside Kyiv, destroying the main station building and damaging rolling stock. Ukrainian President Volodymyr Zelensky condemned the attack as "meaningless from a military point of view," highlighting that the Russians "could not have been unaware of this." These intensified attacks, which also targeted energy facilities in eight regions causing blackouts, coincide with crucial diplomatic efforts to de-escalate the conflict. The UN's nuclear watchdog also reported that the Zaporizhzhia nuclear power plant temporarily lost all external power overnight, marking the 11th such incident since Russia's full-scale invasion.

Amidst this escalation, US and Ukrainian negotiators engaged in a third day of talks in Florida, aiming to establish a framework for security arrangements that could lead to a lasting peace. US special envoy Steve Witkoff and Rustem Umerov, secretary of Ukraine's national security council, described their discussions as "constructive," agreeing on potential security frameworks and necessary deterrence capabilities to sustain a lasting peace. The negotiations, also attended by Jared Kushner, son-in-law of former US President Donald Trump, focused on Russia's readiness to take "steps towards de-escalation and cessation of killing" as a prerequisite for ending the war. The Ukrainian team was briefed on a recent meeting between Witkoff and Russian President Vladimir Putin.

These Florida talks followed a meeting in Moscow earlier in the week where Witkoff spent almost five hours with Russian President Vladimir Putin. Despite the lengthy discussion, the Kremlin stated that "no compromise" had been reached on a draft US peace plan, which had previously been perceived as favorable to Moscow in an initial leaked version. Ukraine, spearheaded by President Zelensky, pushed for revisions to this plan and sought full information on the discussions, expressing skepticism about Putin's commitment to ending the war and his pretexts to "drag out the war." Putin, however, indicated readiness to continue meeting the Americans "as many times as needed."

Major points of contention continue to hinder progress. These include the demand for Ukraine to surrender territory, specifically the approximately one-fifth of its land currently controlled by Russia, including swathes of the Donbas region (Donetsk and Luhansk). Putin, in an interview, warned Ukrainian troops to withdraw fully from the region, threatening to "liberate these [Donbas] territories by force" otherwise. Furthermore, the provision of robust post-war security guarantees for Ukraine and the prospect of its membership in NATO remain highly divisive. While Kyiv and its European allies see NATO membership as a crucial deterrent against future Russian aggression, Russia is staunchly opposed, and Donald Trump has repeatedly signaled his disinterest in Ukraine joining the military alliance, calling it a "key question" in Moscow talks.

The relentless targeting of Ukraine's energy capabilities in recent weeks suggests Russia's intent to disrupt supplies of heat, light, and water as the country braces for a fourth winter of full-scale conflict. Russia’s defense ministry justified its "massive strike" as a response to alleged Ukrainian attacks on civilian targets, a claim vehemently denied by Ukrainian Foreign Minister Andrii Sybiha, who stated that "Russia continues to disregard any peace efforts and instead strikes critical civilian infrastructure." He emphasized that decisions to strengthen Ukraine and raise pressure on Russia cannot be delayed under the pretext of a peace process.

International reactions to the US-led peace efforts have been mixed. While the White House hopes for an end to the conflict, figures like US Vice-President JD Vance expressed "perennial frustration" over the complexity of the war, admitting the administration was surprised by its difficulty. European nations have occasionally felt "blindsided" by US initiatives, yet the EU's foreign policy chief, Kaja Kallas, affirmed the enduring US-Europe alliance, despite differing views on specific topics, including a recent US national security strategy. The path to peace remains fraught with deep-seated disagreements and a lack of mutual trust, making a swift resolution challenging, as highlighted by Trump's comment that "it does take two to tango."
