I remember reading somewhere that Mike had reduced the regimes of Clemenza and Tessio obviously makin'a move out of weakness as it said.

1. How exactly was Mike reducing the strengths of the 2 regimes of the Capos (Captains)? Was he firing some of the Button Men that seemed useless to him? Or what?

2. Why was he makin' the move out of weakness? was it just to fool His rivals? Mainly Barzini? What's your take?
