Justifiable Conquest?

It is never easy... again; I believe that there is no nation where, if the people want they can remove a government. A populist movement will include enough of the military to remove its power structure as well.
Something that has always bugged me about Mexico, with their infrastructure, their amazing natural resources… it just seems like they (as a nation) don’t want it badly enough.
What is the trend? Go to another nation to make it and send the scraps back instead of building yours up from within, where is the pride, the honor, the taking responsibility for your Nation in that?... no thanks.
