i think that wars are bad in any way...people should understand each other, otherwise no one will be satisfited...if someone for example wants to regain their land, they shouldn't make a war...they could solve their problems in an another way...others make a war to expand and most commonly for reasons we might not understand but are important to powerful governments. However some popularities like the muslim community fight for their religious beliefs. For example the terrorist attack in the twin towers on the september the 11th.
