Ukraine Counteroffensive Aided by High-Tech NATO Weapons

Ukraine has launched an offensive, regaining control of eastern villages around Donetsk. Following accusations of Russian ecoterrorism and the destruction of the Kakovka Dam, a massive flood has caused a humanitarian disaster affecting 10,000 people. Russia denies involvement. Prior to the flooding, a joint assessment estimated Ukraine's reconstruction costs at $411 billion. Despite this, Ukraine continues to receive significant military aid, with the UK now the second-largest donor after the US. Ukraine's counter offensive is supported by advanced NATO weaponry, and the scale of the effort is compared to the D-Day landings, indicating a prolonged and sustained operation.
