WHO IS 'THE ONLY ONE' WHO HAS THE POWER TO SET THINGS STRAIGHT IN AMERICA AND THE REST OF THE WORLD ?

It will not be Donald Trump or the Republican Party. Donald Trump tried his best, but he was betrayed by the RINO Republicans, and he is not powerful enough to do it alone, but this 'ONE' is :

Revelation 12:5

"And she brought forth a man child, WHO IS TO RULE ALL NATIONS with a rod of iron and her child was caught up unto God, and to His throne."  

Jesus was "caught up unto God" on  Ascension Day which was forty days after His crucifixion. That was the last day of His First coming on earth. Since that day, the affairs of mankind on earth have  been left for man to solve on his own, but that gross failure is soon coming to an end on the first day of the Lord's Second coming on earth according to :

Revelation  19:15

"And out of His mouth goes a sharp sword (the Word of God ) that with it He shall smite THE NATIONS,  AND HE SHALL RULE THEM WITH A ROD OF IRON ,  and He treads the winepress of the fierceness and wrath of Almighty God."   

SO, THERE YOU HAVE IT :

The affairs of mankind cannot be solved  by man. This fact has been proven time and time again over the past several thousand years of man's habitation on earth. That is all about to end abruptly. Of course, the Second Coming of the Lord has been wrongly predicted  many times over the past years, but the one thing that is for sure is we are closer now than we have ever been. It will catch almost everyone left behind after the resurrection/rapture occurs by surprise.  

According to Your Holy Word, come Lord Jesus !
