National interest in our politics

We always blame various movements of G. W. Bush and Tony Blair but have we ever thought how much shameful the political environment of our country has become? Here, one noteworthy thing is, the contrivance in European and American politics is graceful of national interest, which is quite absent in our politics. In a democratic country there should be position and opposition parties but it does not mean that, the parties should never come to unanimity. In Bangladesh, although having a democratic constitution our political parties are never in agreement, not even for national interest. Recently, some issues on the reform of electoral system and caretaker government have been the matter of political conflict . But I cannot understand, if a successful election is in nation's interest then why there shall be any delay, debate and conflict between the political parties on its implementation. In a democracy the political parties can rebel against any misdeed and wrong decision of ruling party but not through any illogical and detrimental activity though our opposition parties have chosen 'hartal' like vicious activity as a language of their protest. Hartal gives us nothing except loss, it devastates our national assets, makes obstruction in the way of nation's development. In such a condition, can I not say there is lack of national interest in our politics? From my point of view, the politicians have to be much concerned of each national issue and they have to work in favour of various national interests.
