The antichrist doesn't have to be elected king of Israel. No scripture says that. He will rule the whole world.
This is what to look for to identify the antichrist:
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.
2Th 2:5 Remember ye not, that, when I was yet with you, I told you these things?
2Th 2:6 And now ye know what withholdeth that he might be revealed in his time.
2Th 2:7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.
2Th 2:8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:
2Th 2:9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders,
Lying wonders is the same as deceiving miracles. He will perform miracles and will claim to be God. He likely will claim to be Jesus and perhaps other deities people believe in like Buddha and Allah.
If you think a man is the antichrist but doesn't say he is God and doesn't perform miracles then he isn't the antichrist.
