Define 'dialog' Hopping on the first plane after inauguration day for a tour of known opponents? Beginning discussions through an appropriate channel in order to a achieve a specific objective? General discussions, mostly informal around issues with an identifiable common interest. All are dialog but the difference is significant.
One would think that dialogue would start with some sort of informal objectives, mostly humanitarian missions with a general, "Hey, how ya doin? Need help with anything?" But I don't think that it would be the first day after inauguration, that day is left for remodeling the president's new house.
