Yes, sadly, if you look up the definition of the meaning of the slang usage of the word “chicken hawk”... two pictures illustrate the meaning. One is of brave and determined little Henry the Chickenhawk dragging off Foghorn Leghorn.
The other picture is of this vicious clown...
There are two definitions given in the "Urban Dictionary":
1. Older male who seeks the company or favours of a younger male. The term has homosexual overtones.
2. A politician or other person who promotes war without having had any personal experience of it; especially those who have avoided the experience.

Either might describe Lindsay Graham. He technically was a member of the US Air Force for 30 years, much of this time he was unpaid and doing no actual work for the Air Force or the reserves, The closest he came to being deployed to anything resembling combat was when he was attended some carefully arranged stints that lasted a few days and coincided with trips he made as part of congressional delegations.
It does embarrass me that you as a "cold warrior" have no clue what the actual understood meaning of "chickenhawk". The vast majority of Lindsay Grahams 30 years as a "member of the military" shamefully earned points toward an undeserved military pension; he was unpaid as an Air Force officer while a congressman and senator; he was ineligible for a military paycheck during his time in the federal government. He was technically not retired but did not participate in any worthwhile activities with the Air Force, in other words, his long years of military service were mostly a joke.
It is an embarrassment to me that you have made an attempt to mischaracterize Lindsay Graham's time in the military. I am not sure if this is from "simple ignorance" or intentional deviousness.
