Sadly, it seems that does not make people statistically safer. It appears that the prosecution of acts of war for profit are executed offshore - against non-Americans.
Also, I doubt any other governments are less corrupt. Corruption seems quite endemic to the species, both human and systemic, meaning governments.
Hopefully, the new foreign policy will continue to see US forces withdrawn from conflict around the world.
I'd very much like to see a new paradigm come to the fore in terms of business and industry, a sea change from defense and war, to manufacturing and industry.
We'll see.
Hopefully those changes will come to fruition sooner rather than later.
