I think the last verse,

Onward, Christian soldiers! Blight all that you meet;
Trample human freedom under pious feet.
Praise the Lord whose dollar sign dupes his favored race!
Make the foreign trash respect your bullion brand of grace.
Trust in mock salvation, serve as tyrant's tools;
History will say of you: "That pack of G.. D.. fools"

is most apropos in the present crisis. The first verse is great, but only really pertinent when the strife is Christian against Christian. And thankfully it's been quite a few decades since that was significantly the case. The last verse, though, works for everything from the Pledge of Allegiance Wars to the Confrontation With Islamdom.
