How do you say <Holding my hand right now> and the famous quote "World War 3 will be fought with sticks and stones" (by Albert Einestein.)

Thnks a lot !

My try as a learner:

elimi tutuyorum şimdi (I am holding my hand now)

elimi tutuyorsun şimdi (you are holding my hand now)

o elimi tutuyor şimdi (he/she is holding my hand now)

Who is holding your hand?

Sopalı taşlı üçüncü dünya savaşını kavga edecekler

(They will fight the third world war with stick and stones.) 

Wait for corrections 

"World War 3 will be fought with sticks and stones"

1)Üçüncü dünya savaşı sopalar ve taşlarla yapılacak.

2)Üçüncü dünya savaşı sopalar ve taşlarla savaşılacak (literal but weird in Turkish)

We dont say "to fight a war" in Turkish. It is weird. We say "to make a war"

Having paved the way for nuclear weapons that he thought would be popular in WW3, Eınsteın was talkıng about the WW4.
