What are the current military and strategic challenges facing Ukraine in its ongoing conflict with Russia?

Ukraine faces significant military disadvantages compared to Russia in the ongoing conflict. Russia leverages its substantial industrial military capacity to mass-produce low-quality weapons and overwhelm Ukrainian defense lines through sheer volume. The Russian strategy involves throwing massive numbers of men and materials at Ukrainian positions, accepting extremely high casualty rates of over 1,000 daily losses because they have the population and resources to replace them. Ukraine lacks this numerical advantage and cannot sustain such heavy losses. Additionally, international support, particularly from the United States, shows signs of wavering, further limiting Ukraine's resources and personnel. These harsh realities, combined with changing diplomatic dynamics including recent interactions between world leaders, may force Ukraine to confront difficult decisions about pursuing peace negotiations despite their disadvantageous position.
