Kudos for your realism.
It has always struck me as weird that the moment a nation enjoys some stability and prosperity, it immediately decides to throw them away for ever-growing expansionistic ambitions.
I mean I get it, we as humans can never get enough -- I've witnessed that in many people, myself included.
It's just so very sad to observe historically. It seems that if somebody sees they can get away with X, they immediately jump to doing something 10*X.
Ironically, this is the exact scheme through which many criminals have been caught -- they admitted they felt a thrill because they have not been caught, and wanted to up the risk. (The police would have never caught them if they haven't did that as well.) I don't believe the same exact phenomena is involved with nations but if you squint your eyes really hard then it does look very similar.
