In a civilized country it could happen that a new government has to be formed by two rival parties. Take a look at Germany, they got to use this formula (Big Coalition, Grosse Koalition in German) in order to support a massive reforms program in the ’00. In such a situation the National government work under an agreement, a high form of compromise between political rivals. After the end of this agreement everybody is free to compete against each other, democracy is still in its place and the National interest has been preserved.
