As of now the estimate is they have committed 50% to Ukraine, that is pushing hard at the upper limit of how many can actually be committed before there is no logistical support at all. They could go to 2/3 for a short time, but even more of them would be wandering about begging for food than are now. They appear to have made the same mistake as Rumsfeld when invading Iraq, a similar sized country with a similar sized invading force - he tried to go light and immediate reinforcements were required. The difference is the country of Ukraine is better prepared, they have better resolve, and some better weapons, while the Russians have far lower equipment quality, morale, and training. Nonetheless, there is an enormous logistical advantage of attacking a neighbor from three sides and not a country halfway around the world. Ukraine also has much more forgiving terrain for an attacker than Iraq. Everything is up in the air, but I share your optimism that Ukraine could come out on top.
