God is Sovereign and in control of ALL The Nations.
Jeremiah 18:7-10 NKJV
The instant I speak concerning a nation and concerning a kingdom, to pluck up, to pull down, and to destroy it,  if that nation against whom I have spoken turns from its evil, I will relent of the disaster that I thought to bring upon it.  And the instant I speak concerning a nation and concerning a kingdom, to build and to plant it,  if it does evil in My sight so that it does not obey My voice, then I will relent concerning the good with which I said I would benefit it.
Gods Word is reliable.
Daniel 9:3-5 NKJV
Then I set my face toward the Lord God to make request by prayer and supplications, with fasting, sackcloth, and ashes.  And I prayed to the LORD my God, and made confession, and said, “O Lord, great and awesome God, who keeps His covenant and mercy with those who love Him, and with those who keep His commandments,  we have sinned and committed iniquity, we have done wickedly and rebelled, even by departing from Your precepts and Your judgments.
God keeps His Word.
Jeremiah 29:11-13 NKJV
 For I know the thoughts that I think toward you, says the LORD, thoughts of peace and not of evil, to give you a future and a hope.  Then you will call upon Me and go and pray to Me, and I will listen to you.  And you will seek Me and find Me, when you search for Me with all your heart.
Matthew 24:14 KJV
And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
