Ukraine Air Defense Degrades as Front Stalls; US Mediation Fails

Ukrainian air defense effectiveness is declining, per Col. Lewandowski, while front-line dynamics show Ukrainian forces under pressure near Orechowe and Russian propaganda masking lack of progress near Lyman. A fresh US mediation attempt has failed, indicating no near-term diplomatic off-ramp. This suggests deteriorating Ukrainian defensive capacity and a protracted conflict with continued attrition.
