Russia has a population just under 200 million people and the Ukraine has just over 40 million. The Ukraine is about 600k km2 and Russia is 1.7 times the size of the USA. This would make the Ukraine about the size of Texas, a bit smaller, actually. Russian missiles can hit any part of the Ukraine from Russia. The Russians have at least enough missiles to put at least 50 missiles into every major city in the Ukraine. This is only if our intel about the Russian inventory is correct, which is doubtful. This also doesn't take into account the bombers and both smart and "dumb" bombs. If Russia really wanted all out war, they could wipe the Ukrainians off the map. This indicates a substantial amount of restraint on behalf of the Russian offensive. Therefore, I believe Putin when he states that he is trying to attain specific goals in this offensive and is not trying to wipe out the Ukrainians and take over the country. We will have to wait and see what he does when he completes the mission and see if he withdraws all his troops.
