^ I agree with your last point in particular. Laws, regulations are not passed and decisions are not taken with the understanding that a party may not be in power after 5 years. Unfortunately, this unilateral attitude is supplemented by our opposition, which usually refuses to sit at the same discussion table.
For example, when I was doing research on, what is now, our latest constitutional amendment, the current Speaker of the Parliament, Abdul Hamid MP, expressed how he had approached the BNP on numerous occasions to discuss the then proposed amendment but they refused to cooperate.
As you say, its not healthy for our democracy if we're not able to break out of this impasse
