the defensive line in west of Ukraine are significantly weaker than east which in last 8 year was effectively at war .and no getting Romania and Poland won't be on agenda . here its said that Russia can ask Belarus to attack west of Ukraine and cut the supply lines there and if the defense there with Belarus is all based on border guard and mines it means there actually is no defense there against a full military invasion from that front.Easily? Ok then why not do it today? Probably it was Putin’s grand plan. It’s just the entire western side from Poland and Romania to take. I double the Russians can they still struggle since months to take Bakhmut still no success.
and bakhmut only become bakhmut because unlimited amount of ammunition delivered to Ukrainian forces there , if NATO support line got disturbed in western Ukraine then the situation for Ukraine force change dramatically
