Israel is backed by God's divine powers...the Bible clearly illustrates this FACT (NOT AN ASSUMPTION) repeatedly. And it has been demonstrated many times since 1948.
Had they no weapons, the muslims would have already overrun them. God has a timetable. Everything happens on HIS schedule. Even with nuclear weapons, it will take the Creator Almighty God to protect them when all the nations of the world come against them. After they realize Jesus is the Messiah, God's powers will be on full display, so that no one in the world doubts it.
