That does not mean that it is up to the US to ensure that right, and it cannot even if we wanted to. The world is not ours to remake.
“...The world is not ours to remake.” [Pining_4_TX, post 28]
A precious moral sentiment. Americans are far too inclined to believe it. If we do not remake things, others will. Are we so sure we will like the results of that?
The United States was a trading nation before it became a formally sovereign, independent nation. Stray remarks by the Founders notwithstanding, trading nations cannot be isolationist.
The time to intervene is before things get really bad. The dire situations that developed in World War One, and then World War Two, should give us a hint.
But too many Americans are too enamored with their own moral state to notice. Conservatives pride ourselves on being realistic; we should be leading the way on incidents like this, not congratulating ourselves on our moral prissiness while opting out.
Citing past incidents where intervention did not end well is excuse-mongering of the most puerile variety.
