How to run an opposition

In Israel, the Prime Minister stands up and says, “Enough. We have to prevail.” And then the leader of the opposition party gets up and says:

The prime minister must “not do half a job, he must finish the job” against Hizbullah, said Netanyahu. “Israel must learn their lesson this time – a decisive victory without concessions to eliminate Hizbullah once and for all.”

I wonder what it’s like to live in a country where “opposition” means opposed to the other party and not to the country itself.
