What recent developments indicate the escalating tensions in the Russia-Ukraine conflict and how is the U.S. responding to the situation?

The conflict between Russia and Ukraine has intensified with Ukraine reporting 133 Russian drone attacks overnight, demonstrating Putin's continued military aggression despite claims of readiness for peace talks. President Zelensky directly contradicted these peace assertions, stating that Putin is "preparing to continue deceiving the world" rather than genuinely negotiating. The U.S. response reveals mixed messaging from the White House regarding their position on ending the war. Vice President J.D. Vance indicated potential escalatory measures, including sanctions against Russia and even the possibility of deploying U.S. forces to Ukraine if Putin fails to negotiate in good faith, highlighting the complexity of American foreign policy toward this ongoing conflict.
