Christian propaganda? Okay, put yourself in the first century and describe an attack helicopter or a tank.
Isa 11:9-11
9 They will not hurt or destroy in all My holy mountain,
For the earth will be full of the knowledge of the LORD
As the waters cover the sea.
10 Then it will come about in that day
That the nations will resort to the root of Jesse,
Who will stand as a signal for the peoples;
And His resting place will be glorious.
11 Then it will happen on that day that the Lord
Will again recover the second time with His hand
The remnant of His people, who will remain,
From Assyria, Egypt, Pathros, Cush, Elam, Shinar, Hamath,
And from the islands of the sea. NAS
In that day the Hebrews will return to Jerusalem and God will fulfill His covenant with Abraham, Isaac, and Jacob. In other words the God of the Bible will be in control not the miriad of avatars proposed by false religions.
