From around 1947 or so. Seems particularly apropos, if not entirely accurate, on several fronts today.

No Holy Wars for Them

Robert Frost

States strong enough to do good are but few,
Their number would seem limited to three,
Good is a thing that they, the great, can do,
But puny little states can only be.
And being good for these means standing by
To watch a war in nominal alliance,
And when it's over watch the worlds supply
Get parceled out among the winning giants.
God, have You taken cognizance of this?
And what on this is Your divine position?
That nations like the Cuban and the Swiss
Can never hope to wage a Global Mission.
No Holy Wars for them. The most the small
Can ever give us is a nuisance brawl.
