As I'm currently playing through SWTOR as a Vanguard and reading the Republic Commando books I've started to wonder why it is that the Republic thinks that the Sith are completely defeated, let their army deteriorate, and are shocked when the Sith return (again). This goes on for the 25,000 yrs of the Republic until it finally falls to Palpatine. In the case of the Clone Wars, the books explicitly state that the GAR is almost entirely clones, with very few volunteers. How does no one in the Senate see the need for a strong standing army, particularly near the end of the Old Republic when Bethany Wessen finds out that the Clone Army came out of nowhere and previously the defense budget was negligible? The first few times are understandable, but this literally happens every few centuries for 25,000 yrs. How is this a surprise every time?
