I think wretchard and old blue have a good take on the situation. Logistics and having already achieved ones primary goals are a good reason to hold up. They can continue and take the rest if they so choose in the future but there is no reason to screw it up at this early a stage. They can consolidate as they hold some very powerful cards still. They can also watch and see if the West actually mobilizes.

BTW, is there a difference between Wretchard and Richard? I thought they were one and the same…
