The Clone Wars were a long series of battles between the Republic and the Confederation of Independent Systems. A series of battles actually constitutes a war, but "wars"? And there were multiple Clones involved, so shouldn't it be Clones War? Makes no sense!
At the time of the Clone Wars, there was much debate among the senate as to the cost of the war. A prominent senator was accused of claiming that the Clone Wars cost nothing. In actuality, he claimed that they would cost next to nothing, since the Republic did not need to pay for the army of clones, and already had a lot of the equipment. Critics pointed out that many of the Jedi would require payment, and money would have to be spent on promotional materials and transportation. The Emperor felt that the Republic could afford to make an expenditure since he saw potential for a longterm profit.
