In 2024, global military spending reached its highest level in decades—
Global military spending reached its lowest point of $1.2 trillion in the late 1990s. Since then, military spending has more than doubled, reaching $2.7 trillion in 2024.
The chart shows a drop in military…
If anti-Catholicism was heavily punished as “phobia”, we’d never have the Reformation.
If anti-Christianity was strictly policed, no Enlightenment.
