You are confusing political systems with democracy. The ideals of democracy are universal. Countries get to choose what political systems suits their needs and circumstances.
The democracy in Britain has the same thing in common with the democracy in the US, France, Germany, Australia, Botswana, Japan etc.
How those great democratic countries are administered may be different, but the bottomline is that their democratic ideals are very similar.
It’s kind of blunt way of putting it “democratic ideals are very similar”, I'm not sure what you meant democratic ideas. Let me tell you this, once upon a time there was unofficial new world order known as east vs west. Countries which took legion to US were known as the WEST and others took legion to USSR were known as the EAST. The countries which chose US shared their secrets, trade, defence, culture, research, education, even people to people contact was simplified. African was not part of those settings, but Africa was used as playing ground for those two large groups. What happen in Africa then, is what is happening in middle east today.
So, from the outside you might think their achievement is the direct result of their democracy. Well…. you're wrong, their achievement came from the huge investment they made in science and technology, it came from opening up trade among themselves something which Africa has failed to archive. None of their achievement came from politics, China today is investing more money in R&D only second to US and the results are there for all of us to see. My point here is, we can't be lazy enough to think that western style democracy will solve our problems. The rise of far right movement in western world is a clear indication that those democracies are failing. They are failing in safeguard human rights, failing in trade (protectionism is name of the game), security hasn't been this low, future is full of uncertainty.
We need to clear some obstacles in our political system or so called democracy, we need to do away with tribalism, regionalism, regionalism, gender, favouritism, corruption and many more. We need to educate our people to be aware of their democratic rights, and we need to reduce voices in our political system, some leaders can be elected with council of leaders or elders. System has to be transparent just like the high courts do with high profile cases you where number of judges determines the outcome of the case but their judgement is laid bare for everyone to see. We need a simplified mechanism of changing the leader who did not meet people expectation, we need to unite and speak with one voice in times of crisis, and on top of that, we need to increase level security to protect our democracy from the outside influence.
