Jordan overpowered South Korea and a "devastated" Son Heung-min 2-0 on Tuesday to reach their first Asian Cup final and a showdown with Iran or hosts and holders Qatar.
Playing in the semifinals for the first time and ranked 64 places below their opponents, Jordan fully deserved their victory over Jurgen Klinsmann's shell-shocked side.
South Korea failed to have a shot on target and their talisman Son apologised afterwards as his country's wait for a first Asian Cup since 1960 goes on.
Jordan deservedly went ahead soon after the break, Yazan Al-Naimat scoring his third goal of the tournament after South Korea gave the ball away cheaply.
They had been in a losing position in four of their matches in Qatar, but there was no way back this time for the Koreans when Mousa Al-Tamari sliced his way through the South Korean defence 13 minutes later.
South Korea simply could not handle the lively attacking duo of Naimat and Tamari.
"Actually I was dreaming about this tournament before, when I was in France," said the 26-year-old Tamari, who plays for Montpellier in France and was named man of the match.
"It means everything to me to be in the final and I hope we can do it in the final," he added, having also set Naimat up for the first goal.
"It's also good to be in the final because it will make everyone speak about my country in France and this is very emotional for me."
South Korea's skipper and Tottenham ace Son stood alone with his hands on his hips at the final whistle.
"Very disappointing, devastated about this result," the 31-year-old told beIN Sports.
"We were a little bit nervous – the guys did not want to make a mistake."
Coach Klinsmann, who agreed with Son that the better team won, had made it his stated goal to reach the final in Qatar.
Asked by AFP if he will now quit, the German said: "There was a lot of good stuff we saw.
"It is a team that is growing and still needs to develop towards the next World Cup.
"There is a lot of work ahead of us. Apart from that, I am not thinking of anything."
'DEFEND THIS SHIRT'
Jordan were the underdogs –even though the teams drew 2-2 in the group phase – but they had the better of an entertaining first half.
In front of 43 000 at Ahmad bin Ali Stadium, South Korean goalkeeper Jo Hyeon-woo was busy almost from the off, saving from Noor Al-Rawabdeh after good work from Tamari.
Jo kept out a fierce drive from Naimat after the South Korean defence opened up, before the ever-dangerous Tamari blazed over the bar.
South Korea were awarded a penalty on the half-hour that was overturned after the referee consulted the pitch-side monitor. Lee Jae-sung pinged a header onto the post.
Naimat went up the other end and slalomed his way through three weak Korean challenges before drawing a close-range stop from Jo.
Jordan took the lead on 53 minutes when Park Yong-woo gave the ball away, Tamari ran towards goal and slipped in Naimat, who popped a cool finish over the advancing Jo.
South Korea could not cope with the rampaging duo and on 66 minutes Tamari drove to the edge of the box before unloading past an exposed Jo.
Jordan's Moroccan coach Hussein Ammouta said his players "delivered a heroic performance".
"What you saw today was the fruition of several years of work," he said.
"We must defend this shirt with everything we've got.
"We are growing more ambitious by the hour."
Iran and Qatar play on Wednesday for the other spot in Saturday's final.
