From Herman Mayfarth comes a reminder that Tom Lehrer had it right in 1965 in this 1 minute 13 second video:
The heart of the lyric, the propaganda rationales, applies 49 years later as it applied then:
When someone makes a move
Of which we don’t approve,
Who is it that always intervenes?
U.N. and O.A.S.,
They have their place, I guess,
But first send the Marines!
We’ll send them all we’ve got,
John Wayne and Randolph Scott,
Remember those exciting fighting scenes?
To the shores of Tripoli,
But not to Mississippoli,
What do we do? We send the Marines!
For might makes right,
And till they’ve seen the light,
They’ve got to be protected,
All their rights respected,
‘Till somebody we like can be elected.
Members of the corps
All hate the thought of war,
They’d rather kill them off by peaceful means.
Stop calling it aggression,
O we hate that expression.
We only want the world to know
That we support the status quo.
They love us everywhere we go,
So when in doubt,
Send the Marines!
