Should the writer put "the" before "push"?

1) That's typical grammar for headlines. The articles "the," "a" & "an" are frequently dropped. So it's perfectly acceptable for a headline, but yes ordinarily you would say or write "holds off the push." And you are also correct about the use of the word "push" in this case.

2) Doubtless there are people who've described them as such. What is the question, specifically?

Oristar, the second sentence appears to be a headline as well, if it were an ordinary sentence, it ought to read:

During WWII, a woman who served in the Japanese army as a sex toy/sex worker/prostitute was called a "comfort woman."

the 'comfort women' didn't serve in the Japanese army but were prisoners, abused by them and forced to work in brothels as prostitutes for the soldiers.

I rather think that Oristar refers to something he has read, as opposed to offering that as a statement which he supports.

yes - I wasn't blaming him personally!! just correcting the sense of the sentence, which implies something rather different fromt he facts.

Thanks Monger and Setanta, I've learned of a "new" rule for headline now.

Regarding the compound noun "comfort woman", both Vivien and Setanta were correct. That was a "proper noun" used by the Japanese army, a symbol of deadly destroying Human Rights. I just wanted to know its correct expression in English language, not refered to the facts that Vivien has claimed here.
