Listen to this while reading my post. Why? Because music has psychosomatic effects that are imperative to this post.
Let's assume that, hypothetically, we have the funding for such an endeavour (via taxing every affluent country in the world as well as every country in the UNSC), is this idea fundamentally flawed or fundamentally sound?
I think that it is a fundamentally sound idea. Given that Human Rights are universally recognized as something that all humans generally would prefer to have, a world police force (let's call it the Justicars for the sake of this argument) given the mandate of preserving these human rights across Earth would be a great idea. From the genocide in Darfur to the plight of the Rahkine in Myanmar to the plight of Syrians at the hands of Bashar Al-Assad in Syria, immense injustices would be avoided. Countless atrocities currently pending and even those that may have yet to come would be terminated by such an organization.
Furthermore, I realize that the United States is the closest thing to a world-wide police force right now, but even they fail at doing this properly (especially considering that some Americans seem to be tired of this) as they have not aptly intervened in places like Darfur or Myanmar as well as they could have.
If the Justicars could be regulated, audited and safeguarded against the creeping of corruption, I don't think any rational-minded person could claim that this is not a conceptually great idea. All humans are created equal, are equal, and should be entitled to at least some degree of justice in their however injustice-marred lives.
Thoughts?
