Revelation was written by St. John during the 1st century AD when no weapons of modern warfare existed at all.
By definition, it's called a revealed religion because God had revealed such prophetic visions to John during the 1st century.
How was John to interpret the futuristic scenes of carnage, death, and destruction from the two world wars?
Obviously, he would use his own language and culture to try to describe the modern weapons, such as nuclear weapons, biological weapons, mustard gas, long range missiles, tanks, aircraft, battleships, artillery, and small arms, etc.
Rather than try to invent 'new' words to describe such modern weapons of warfare, John would stick to his own language and culture instead.
Knowing that these are futuristic images of real weapons, John would use his own language and culture to try to describe such weapons.
The most common ancient weapon being the sword John would've used the image of a "sword" to try to describe the entire inventory of modern weapons, which had no modern names at all during the 1st century.
However, I think that your attempt to avert WW3 will ultimately fail, because there is no reason to assume that John wasn't talking about the weapons of modern warfare due to his divinely inspired prophecies of the future Armageddon.
