It’s very strange how many people here have confidently incorrect ideas about what journalism purports to be or do.

An engineer is someone who develops and implements engines.

What is an engine? Citing Merriam Webster[1]:

>3a: something used to effect a purpose

So yes, an engineer can make implements of war among many other implements. The people who actually wage war are called other things.

Your comment suggests you do not know the English meanings of "make" and "implements". Note that implements is a noun in my above comment.

Also, you've inverted the etymology. Engines are named after the ingenuity of their makers.
