Jehovah will give Jesus the go ahead more likely to intercept than prevent because if he prevented a mass launch it could be said man built them but never really used them.

"I saw also an angel standing in the sun, and he cried out with a loud voice and said to all the birds that fly in midheaven: “Come here, be gathered together to the great evening meal of God, 18 that YOU may eat the fleshy parts of kings and the fleshy parts of military commanders and the fleshy parts of strong men and the fleshy parts of horses and of those seated upon them, and the fleshy parts of all, of freemen as well as of slaves and of small ones and great.”
19 And I saw the wild beast and the kings of the earth and their armies gathered together to wage the war with the one seated on the horse and with his army. 20 And the wild beast was caught, and along with it the false prophet that performed in front of it the signs with which he misled those who received the mark of the wild beast and those who render worship to its image. While still alive, they both were hurled into the fiery lake that burns with sulphur. 21 But the rest were killed off with the long sword of the one seated on the horse, which [sword] proceeded out of his mouth. And all the birds were filled from the fleshy parts of them." Rv19:19
