Answer:
They have kept the country intact
Explanation:
I think this is a very interesting question. In my opinion, I think they have kept the country intact, look at it this way. Political parties means that there exists choice for the people. Absence of political parties makes it a 1 man ruling without the necessary checks and balances. Like in that of a monarchical ruling t, or military ruling. Essentially, one can do and undo as one wishes.
Now, the advent of political parties brings choice, meaning the people can choose. In a situation where party A doesn't fulfill its political campaign promises, they are at risk of being voted out by the people for party B. Party B themselves won't sit down idle, while not in power, they wake the people up to the wrongdoings of party A.
Like I said, the presence of political parties brings choice to the people, and also creates checks and balances. So, yes, they have kept the country intact.
