I believe the Antichrist will come out of the revived Roman empire. He won't be an American.
I also believe Christians will be raptured to heaven before the Antichrist is revealed.
The antichrist,the little horn,the man of sin,will come from the Roman Empire,for in Daniel chapter 7 it states that the Roman Empire did not have their dominion taken away until Jesus puts them down,in which they will come together at the end time,and the world will be split in to 10 sections,which is the 10 horns,and the man of sin will come from the 10 horns,which come from the Roman Empire.
Also in Daniel 9:26,it says the prince to come,will come from the people who overthrew Jerusalem,which is the Roman Empire.
But the saints will be in the tribulation,because the Bible says the saints will not be united with Christ,until there is a falling away,and the man of sin,the antichrist reveals himself to the world(2 Thessalonians 2:1-13)that he has harnessed the power of nature,and gained power,and has the solution for what is best for the world,and the power to make it happen.
This is because that as long as the world can repent of their sins,the saints will remain on earth.When they take the mark of the beast,then repentance is no longer available to them,and God will take His children.
But the Bible says the little horn wears out the saints,and makes war against the saints,and Matthew chapter 24 says after the tribulation,then the saints are resurrected.
Also I do not believe the antichrist will be a person interested in being president,because he is so arrogant that the position of president is beneath him.He will only be interested in being a great man of peace,bringing peace to the middle east to start the 7 years period.
To compete with people for any position,like president,would hinder his agenda as appearing like no other person,that does not compete for any position,for he is above all positions in the world,and there is only one man of sin,and nobody else.
This man will be so heady,so high minded,that it would be an insult to him to compete with other people for a position,because he believes he is above all those positions,any position in the world.
He is being trained in the occult for a position that there is no competition for that,but he is the only one in that position,and it is above all positions on earth,for he believes he will harness the power of nature,and gain power.
Dan 8:23 And in the latter time of their kingdom, when the transgressors are come to the full, a king of fierce countenance, and understanding dark sentences, shall stand up.
Dan 8:24 And his power shall be mighty, but not by his own power: and he shall destroy wonderfully, and shall prosper, and practise, and shall destroy the mighty and the holy people.
Dan 8:25 And through his policy also he shall cause craft to prosper in his hand; and he shall magnify himself in his heart, and by peace shall destroy many: he shall also stand up against the Prince of princes; but he shall be broken without hand.
Dan 8:26 And the vision of the evening and the morning which was told is true: wherefore shut thou up the vision; for it shall be for many days.
Dan 8:27 And I Daniel fainted, and was sick certain days; afterward I rose up, and did the king's business; and I was astonished at the vision, but none understood it.
Dan 11:36 And the king shall do according to his will; and he shall exalt himself, and magnify himself above every god, and shall speak marvellous things against the God of gods, and shall prosper till the indignation be accomplished: for that that is determined shall be done.
Dan 11:37 Neither shall he regard the God of his fathers, nor the desire of women, nor regard any god: for he shall magnify himself above all.
Dan 11:38 But in his estate shall he honour the God of forces: and a god whom his fathers knew not shall he honour with gold, and silver, and with precious stones, and pleasant things.
Dan 11:39 Thus shall he do in the most strong holds with a strange god, whom he shall acknowledge and increase with glory: and he shall cause them to rule over many, and shall divide the land for gain.
2Th 2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
2Th 2:2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
2Th 2:3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
2Th 2:4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
The antichrist would view it as an insult to him to compete with mere human beings for a position that is beneath the position that he is going for,and he is the only one in that position,and there is no competition for that position,which he will exalt himself above all people,and their positions.
The antichrist will begin his work when he brings peace to the middle east,solving what nobody else could solve,and from then on will gain a following,leading to the beast kingdom,where he claims to be God,by harnessing the power of nature,and there is nobody that can compete with him for that position.
Obama,and the presidents,and their positions,are a peon in the antichrist's eyes,although he likes that they deceive which helps him out.
