If that prophecy has come to pass why would not this one coming to pass as well?

3Then shall the LORD go forth, and fight against those nations, as when he fought in the day of battle.

And right now we can see the overwhelming opposition and they are vastly outnumbered but God is a majority of one.
But there is no doubt that war will eventually happen people can see that prophecy taking shape right now.
It's only a matter of when?
