Indeed sadly, logic has no place in this war. Russia looks like it will sit tight, whilst being hit by weapons it cant match. West will slowly move supply to newer and newer systems, as the Ukranians master the tech.
Fortunately, eventually this leads to the russians being destroyed, and the remainder captured or pushed back to the border. Just going to take months.
Sadly then Ukr will need to build a border defense, althought punative raids by Ukr could be the answer to Russian trouble. So as Lavrov said, it will be like Israel and Palestine, only the other way round than he meant.....
