       Ukraine is vowing Wednesday that it’s "ready" after its northern neighbor Belarus – which Russia used as a springboard for its invasion – announced military exercises to assess the combat readiness of their armed forces.

       The Belarusian Defense Ministry said the exercises that began Wednesday would also be used to assess their military’s ability to operate on "unknown terrain in a rapidly changing situation."
