Who is responsible for starting the war in Ukraine?

According to Senator Chuck Schumer, Vladimir Putin is solely responsible for initiating the war in Ukraine, not the Ukrainian people. Schumer emphasizes that Ukrainians have been forced to fight and die on the battlefield to defend their homeland from this aggression. The Senator highlights the staggering suffering and destruction that Ukrainian people and their country have endured. All of this devastating impact on Ukraine stems directly from Putin's actions and decisions to wage war against a sovereign nation.
