sentence: Civil wars can linger on for many years.
sentences_before: Civil wars can be just as destructive and damaging as normal wars between two different countries.
sentences_after: This is because civil wars tend to become complicated very quickly and differ. A civil war might start between two sides, but groups might break up and the new, different sides could start fighting each other. Groups of people who were not involved at the beginning can easily be sucked in, as they start getting weapons to defend themselves against both sides. Civil wars with many different sides all fighting each other have occurred.
