Well, in the past there have been cases where lots of people were eager to go to war.

One of the prime examples is the early days of WWI. Young men on both sides of the war couldn't get into it quick enough, thousands volunteered and cheered when they were shipped off. 

That sentiment changed *very* quickly shortly thereafter.

It really was this. WW1 changed everyone's mentality about war.
