You mean a bad peace like 1939?
I'm thinking more like the bad peace of 1963, 1979, 2001, 2003, 2011, 2011 (again), need I go on?
Yes, but valuearb makes a good point— it is not always true that a bad peace is better than a good war. There are moments when timely, preemptive military intervention can avoid a more destructive conflict. (The problem is, of course, that those moments are often only obvious to us in historical retrospect.)
As anyone who's ever had a war fought on their soil will tell you.
When was the last time a war has been fought on your country's soil? How many times since then has your country brought war to another's?
Your opinion might change were you on the receiving end of these adventures.
