During the reign of LTTE, democracy had been absent, but why was it easy to implement democracy afterwards?

B) The United Nations stepped in to help provide most of the funding to get the country started again and provided them with a Constitution.
C) The LTTE carefully handed over power to democracy in order to maintain peace between citizens.
D) The LTTE had pushed out Al Qaeda and other religious terror groups so there was no threat of an Islamic caliphate or some other form of theocracy.
